Geoff has made many, many appearances on television. Here are all the references I could find. A number of these are courtesy of the Internet Movie Database.
North Beach and Rawhide (1985)- He plays the part of "Tepper" in this forgotten William Shatner flick. That's all I know.
One Terrific Guy (1986)- This movie predates most sexual harassment cases, but still deals with the ostracism a victim faces when she presses charges. No word on Geoff's part yet.
The Abduction of Kari Swenson (1987)- Geoff plays the part of Kari's brother, Paul Swenson, in this real-life drama about the kidnapping of Olympian Kari Swenson by crazy mountain men.
The Tracker (1988)- Geoffrey's a member of the bad posse in this Western about religious fanatics on a killing spree.
My Past is My Own (1989)- whatever this is, Mr. Blake was nominated for an Emmy for his performance, so it must have been pretty good.
Nightbreaker (1989) This is yet another Sheen project. Geoff plays a soldier named "Python" and it is about a neurologist (Emilio Estevez plays the young neurologist, Martin Sheen plays him years later) who must face his conscience years after working on less-than-ethical nuclear projects.
The Keys (1990) I know nothing about this plot, only that Geoffrey stars with Brian Bloom in this one.
Fatal Exposure (1991) This is a suspense/thriller about a woman who picks up the wrong film at the 24-hour photo place. Geoffrey plays the role of Scott.
Maid for Each Other (1992) There's a very bad pun in this title, and Geoff's role is that of Jerry the Locksmith. That's all I know.
Marilyn and Bobby: Her Final Affair (1993) Geoff plays the part of Carl. Carl who? He must be important if he stars!
One Woman's Courage (1994) In this drama about witness protection, alcoholism, and violent crime, Geoff plays Patty Duke's son Ted, a sculptor and auto-accident victim.
Shame II: The Secret (1995) Geoffrey plays death row inmate Gilbert Rawlins in this flick about a motorcycle-riding attorney (played by Amanda Donohoe).
Fast Company (1995) Geoff plays a cop in what looks like some sort of glamourized crime movie.
Max Q (1998) Geoffrey stars as a civilian filmmaker sent to tape a space shuttle mission that goes horribly wrong.
Geoff also made guest appearances on the following shows:
21 Jump Street: 1.4. DON'T PET THE TEACHER as Jeffrey Stone
The Adventures of Brisco County, Jr.: STEEL HORSES as Beck
ALF: SOME ENCHANTED EVENING as Lizard (and believe you me, Mr. Blake's Artistic Integrity Rating went down a few points when I found out this little tidbit)
Alien Nation: GREEN EYES as Michael Bukowski
Any Day Now: In the summer of 1999, Geoffrey played Annie Potts's boss, Glenn, for four episodes.
Bagdad Cafe: Episode 2.7 HELL HATH NO FURY as Clyde
Brimstone: REPENTANCE as Toby Cole
Ed. Note- This program aired on Fox on Jan. 22, 1999. I was in my room. I was watching television. Fox is a channel I actually get. But was I watching this? No. I was half paying attention to some mindless drivel that I think featured the Olsen Twins. This is something for which I will be kicking myself for a very long time.
Civil Wars: 012. WHIPPET TIL IT BREAKS
Dr. Quinn, Medicine Woman: 085. AN EYE FOR AN EYE
Fired Up: YOU DON'T KNOW JACK as Jack Goodman
The Hat Squad: 92 SECONDS TO MIDNIGHT as Jake
Homefront: INFORMATION NEEDED. Email me if you know!
Hunter: 13. SON AND HEIR as Benny Gore
It's Garry Shandling's Show: INFORMATION NEEDED. Email me if you know!
LA Law: Yes, you guessed it, INFORMATION NEEDED. Please let me know!
Matlock: 103. THE CRITIC as Sam Spelldon
NYPD Blue: LOST ISRAEL PART 2 as Dr. Franklin Jones
Renegade
Blake appeared as Hound Adams in the following episodes:
23. THE HOUND
35. CHARLIE
37. HOSTAGE
46. THE TRIAL OF RENO RAINES (part 2)
80. HOUND DOWNTOWN
Star Trek: Deep Space Nine:
34. PLAYING GOD as Arjin
Deep Space Nine's Terry Farrell had this to say about the episode: "Geoffrey had played my boyfriend on [the TV series] Paper Dolls. Isn't that cool? We had already established a rapport, and those don't go away. It was a good character study show."
Strange Luck: LAST CHANCE
Temporarily Yours: INDEPENDENCE DAY as Dennis
You Again?: THE TOUR (?) as Alex (Ed. note: I found information on this in a German episode guide. I got a D in German, but from what I gather, this was a short-lived sitcom featuring John Stamos, and Geoff plays a teenage friend.)
