While we all know where Gillian Anderson and David Duchovny are, The X-Files has thrown up many memorable guest appearances over two decades. So, we open up a very special X-file on where those stars are and what they're up to now. The list has been presented by Digital Spy.
Rebeca Toolan - Teena Mulder
Toolan hasn't made too many appearances since leaving the role of Fox's mum in 2000. She has played Mrs Claus in two TV movies whilst she has appeared in all five instalments of Murder, She Baked from the Hallmark Movies & Mysteries channel from 2015-2017.
John Neville - The Well-Manicured Man
Neville had racked up an impressive five decades of on-screen performances. He continued for another ten years after the show but, sadly, died in 2011 later after battling Alzheimer's for some time. Neville was awarded the Order of Canada in 2006.
Don S Williams - The First Elder
He starred in 14 episodes, along with the first movie. He only starred in one film after his work as a member of the Syndicate, the Ben Affleck film Reindeer Games in 2000. Don has been living with Parkinson's for some years, and is currently living in a care facility. He recently celebrated his 80th birthday.
Veronica Cartwright - Cassandra Spender
Cartwright played the first human to be successfully hybridized with extraterrestrial genetics. Her later career has been consistent, if a little unspectacular. Curiously, she cameoed in the 2007 remake of Invasion of the Body Snatchers (she starred in the 1978 remake) and her regular role in the short-lived show Invasion which was loosely based on the same premise.
Steven Williams - Mr X
Such a powerful regular character, he even managed to come back after death – no mean feat. After this, Williams has remained a staple of American television, most memorable playing Rufus Turner in Supernatural and Virgil in The Leftovers.
Robert Wisden - Robert Patrick Modell
He appeared in '96's' Pusher and two years later in Kitsunegari. The English actor Wisden continued to work solidly until the mid-Noughties when he graduated with a teaching degree. He is now the Head of Theatre Arts at St. George's School in Vancouver.
Robert Patrick - FBI Agent John Doggett
Since 2002, when his FBI career came to an end, Patrick has continued his diverse and fascinating career. Interestingly, he's played two music legends' dads – in the 2005 Oscar-winning Walk The Line he was he was Johnny Cash's father, and he also portrayed Vernon Presley in the mini-series Elvis. Recently he starred as part of the main cast in From Dusk till Dawn: The Series and The True Blood. Patrick is currently appearing on horror anthology Lore on Amazon. (Digital Spy didn't mention Scorpion TV show, as Patrick's favorite one.)
Nicholas Lea - Alex Krycek
After The X-Files, the television work didn't stop, with regular roles in Andromeda, CSI, Kyle XY and the US version of The Killing amongst countless other guest appearances. At the moment, he is part of the cast of the Netflix reboot of '90s kids show ReBoot, called ReBoot: The Guardian.
Mimi Rogers - Diana Fowley
Former scientologist Rogers joined the show in 1998 and her career since makes for a fascinating look with straight-to-video fodder such as Cruel Intentions 2, the dire Dumb and Dumberer: When Harry Met Lloyd, and playing Ashton Kutchr's mother Robin Schmidt in Two and A Half Men. Rogers is a keen poker fan and can be seen round the world at many tournaments. Fun fact: she was Tom Cruise's first wife.
Melinda McGraw - Melissa Scully
Dana's sister has worked continuously since leaving the show in 1997, with recurring roles in shows such as The West Wing, Mad Men and NCIS. Melissa can currently be seen alongside Philip Glenister and Brent Spiner in Fox horror series Outcast. (Melinda and Gillian "reunited" themselves in Crisis (2014) as Julia Devore and Meg Fitch.)
Laurie Holden - Marita Covarrubias
Though Holden starred in a number of big Hollywood films after her time on the show ended (Fantastic Four, Silent Hill, The Mist), the actress found success on the small screen on The Shield, The Americans and The Walking Dead. She's back on the big screen this year alongside Mel Gibson in Dragged Across Concrete.

She's back on the big screen this year alongside Mel Gibson in Dragged Across Concrete.
Jerry Hardin - Deep Throat
We discovered Deep Throat's real name was actually Ronald. Currently pushing 90 years old, Hardin is not as active as he was though he will be seen later this year as author Mark Twain in TV movie, At the End of the Santa Fe Trail.
Darin Morgan - Flukeman
The monstrous star of the 1994 ep 'The Host', Morgan was the younger brother of producer and writer Glen Morgan. Darin joined the writing staff very quickly though did star again on the show as Eddie Van Blundht in 1997's 'Small Potatoes'. His acting career was overtaken by his writing and producing career, with Bionic Woman, Fringe and Millennium all shows he worked on in some capacity.
Cary Elwes - Brad D Follmer
Playing the FBI Assistant Director in the show's later years in its first run, Elwes was not content with his prolific film, TV and voice over career (Saw, A Christmas Carol, The Adventures of Tintin: The Secret of the Unicorn) and moved into writing. As You Wish: Inconceivable Tales from the Making of The Princess Bride was published in 2014 whist his screenwriting debut came in the same year with Elvis & Nixon, starring Michael Shannon and Kevin Spacey.
Brendan Beiser - Pendrell
Beiser's final appearance as the Scully-loving FBI agent came in 1997 but roles in recent times haven't exactly been notable, with characters such as "Surgeon" and "Friendly Guy" on his resume (for Designated Survivor and Orphan Black, respectively). If you're eagle-eyed, you might have spotted him as "Reunion Friend" in this year's Matt Damon flick Downsizing. (He attended the William Davis Center for Actors' Study in Vancouver, where he studied under William B. Davis.)
Adam Baldwin - Knowle Rohrer
As soon as Baldwin was out, he was part of the crew of Serenity in Firefly as Jayne Cobb. More genre roles came in Stargate SG-1, Angel and Chuck whist his voice career boasts an impressive array of characters, including Superman. However, Baldwin is widely attributed as the instigator of the controversial hashtag #GamerGate in 2014 and he doesn't hide his anti-political correctness stance. He's also a Trump supporter.
Brad Dourif - Luther Lee Boggs
After playing the chilling psychic murderer in Beyond the Sea, Dourif voiced the titular doll in the Chucky franchise (again) and provided a memorable turn as Wormtongue in the Lord of the Rings films. On television, he starred in HBO's Deadwood and popped up in the likes of Millennium, Agents of SHIELD and Once Upon a Time.
Brian Thompson - Alien Bounty Hunter
After leaving in 2000, Thompson made guest appearances in Charmed, Star Trek: Enterprise, Californication (where he was reunited with David Duchovny) and in an NCIS ep titled The Truth is Out There (where, in another nod, he played a character called Master Chief Vince Nutter – named after producers Vince Gilligan and David Nutter). He was most recently seen last year in an episode of Seth McFarlane's The Orville.
Steve Railsback - Duane Barry
Despite a memorable role as former FBI agent turned psychiatric patient in a season two two-parter, Railsback's career has perhaps not been stellar; with the likes of 1996 Pamela Anderson movie Barb Wire and American Pie Presents: The Book of Love on his CV. In the past decade he has guested on TV shows Supernatural and The Mentalist.
Luke Wilson - Sheriff Hartwell
Wilson's TV debut came as a vampire in the 1998 ep Bad Blood (though he'd already hit the big screen in Bottle Rocket and Scream 2). He continued his cinematic relationship with Wes Anderson (Rushmore, The Royal Tenenbaums) whilst also starring in box-office fodder Legally Blonde and Charlie's Angels (and their sequels). In more recent times, his star has certainly waned with a lead in Cameron Crowe's short-lived TV show Roadies unable to revive his career.
Doug Hutchison - Eugene Tooms
After just two appearances – Squeeze and its follow-up Tooms – Hutchison would go on to star in '90s blockbusters Con Air, Batman and Robin and The Green Mile and then recurring roles Noughties TV shows Lost and 24. This decade has not been so kind to the actor and, somewhat controversially, his third wife was 16 years old when they married in 2011 (34 years his junior). She filed for divorce earlier this year.
