When I looked up Gary Sinise’s filmography so that I could do his birthday write-up, I was surprised to find that, at the time of this writing, he has only been in just over forty TV shows and movies. Sinise studied at the State University of New York, and in the 1970s he founded the famous Steppenwolf Theatre Company with two of his friends. Throughout the 70s, Sinise mostly worked in theatre, and in the 80s he made the transition to television, with early credits including roles on the shows Family Secrets, Crime Story, and American Playhouse. In the 90s, he moved into film, and won much acclaim for his role as Lieutenant Dan in Forrest Gump. Other notable film roles played by Sinise in the 90s include parts in Ransom, Snake Eyes, The Green Mile, and Apollo 13. Sinise continues to work in TV pretty extensively as well, having starred in the mini-series adaptation of Stephen King’s The Stand, and currently starring in CSI: NY. Gary Sinise turns 57 today.
