Peter Weller started off early in his career with his first film feature in the 70's. But let's focus and begin with 1984 and a little film called The Adventures of Buckaroo Banzai Across The 8th Dimension, which was his first film to be adapted into a comic book. This Film wasn't received well by critics though today it maintains a hefty cult following. Along with John Lithgow his nemesis, Weller a Muscian/Surgeon/Scientist/Samurai/Hero hops across the planet and dimensions to save the world from an alien invasion.
His next major Film successes were Robocop and Robocop 2 (the next of his films to be adapted into a Comic Book). While there were other Films in between, these two were by far his most widely received and loved by movie goers. As Alex Murphy, a former Detroit Cop turned OCP Cyborg in an assassination attempt, Murphy regains control of himself and the city he fought so hard to save.
As Joe Hendricksson, he battles screamers, essentially self aware robots created to eliminate the enemy and now kill anyone, no matter what side they fight for. While this film never made much of a splash, or had its own Comic Book. It was a popular short story by Phillip K. Dick. I, personally, loved this movie. He has such great lines and he delivers them so well. Who remembers, "Well wake up man! We are betrayed here brother! We are beached! We're Stuck! You heard that kid. Green's been shit-canned and this whole GD place is a lie!" Well I do and it still makes me tingle.
Recently J.J. Abrams recognized his gravitas and talent and cast him as Admiral Marcus in Star Trek: Into Darkness, where he delivers lines that obscure the other actors. "If it means anything, I was never gonna spare your crew." (Also adapted into a Comic Book)
He's also known for (and I'll just list the main two):
Batman: The Dark Knight Returns, Part 2 (Video)
Batman / Bruce Wayne (voice)
Dexter (TV Series) (Also adapted into a Comic Book)
Peter Weller is up there with greats like Micheal Caine, Robert Redford and so on in my opinion. He was just never given the chance to redeem himself until recently. Back in his salad days, you had just one Box Office Flop you career could be over. Today, it's a different landscape. And in part we have Abrams to thank for bringing him to a younger audience. And Weller himself to thank for sticking with it and still lighting up the Silver Screen!
