If you've seen my review of The Black Hole, you'll know why I picked Mr. Forster for the actor birthday today. Always a cool presence, Robert Forster's been in all kinds of films, from his debut, Reflections in a Golden Eye (1969) which also starred Elizabeth Taylor and Marlon Brando, to Medium Cool (1969) where he plays an opportunistic news reporter, to Justine (1969) which also starred Anna Karina). He even joined Chuck Norris in The Delta Force (1986). In 1997, Forster was nominated for Best Actor for his role in Quentin Tarantino's Jackie Brown. A versatile and prolific actor, his career is definitely worth looking into.
Here you can see him in the opening scene of Medium Cool.
