Michael's surname, Biehn, is pronounced "Bean".
Michael has starred in three James Cameron Movies; The Terminator (1984), Aliens (1986) and The Abyss (1989). In each film James has had Michael be bitten on the hand by another character.
Michael reprised his role of Kyle Reese in Terminator 2: Judgement Day (1991), appearing in a dream sequence with Sarah Connor. This scene was cut from the theatrical version of the film, but was reinstated on the special anniversary DVD.
Michael was nominated for 'Best Actor' at the Saturn Awards in 1987 for his role in The Abyss.
Michael is 6' (183 cm) tall.
Michael was raised as an Episcopalian.
Michael has said his favorite roles were Kyle Reese in The Terminator (1984) and Johnny Ringo in Tombstone (1991).
Michael has four sons; twins, Devon and Taylor, with his first wife and two younger boys, Caelan and Alexander, with his second wife.
Michael provided the voice of Michael McNeil in the video game Command and Conquer: Tiberian Sun, which was released in 1999.
In preparation for his role as Lt. Hiram Coffey in The Abyss (1989), Michael, along with his fellow cast mates, became a certified diver.
Michael replaced James Remar as Corporal Dwayne Hicks in Aliens, in 1986, after filming had already began. In the scenes where the marines are first exploring the alien nest, any shots of Hicks from behind are actually James, because re-shooting the whole scene to include Michael was deemed too expensive.
Michaels image as Kyle Reese from The Terminator was used as a cover art base for the Metal Gear video game in 1987.
Michael was considered for the bad guy role of the T-1000 in Terminator 2: Judgement Day (1991), but this was deemed too confusing for viewers.
Michael replaced Michael Madsen in the role of Sean Harrison on the short-lived 2004 TV show, Hawaii.
Michael: I had a weird situation were someone used my name to extort money from a woman. He took her for 60 or 80 thousand dollars. He is in prison now. It was on Sally. She thought she was going to marry me and sent money to pay debt I didn't have.
Michael: I am like a mini-producer, they can't keep me down. I am not, but I think I am. No one listens to me. These are just opinions I have. They can't stop me from doing it.
(after being asked to narrate a film for the UDT/SEAL Museum, in Florida)
Michael: Awesome. I was honored to be chosen, I am very proud of it and proud to be a part of something so important. I feel like it is my contribution to our country after the tragedy of September 11, 2001.
Michael: I'd rather have a small part in a good film with good people than play the lead in something I don't really care for.
(just before his fiftieth birthday)
Michael: I've been telling people that I'm fifty for the past two years so I could get used to it.
Michael: If I had to do my life over again I never would have started drinking.
(on whether he prefers playing good guys or bad guys)
Michael: I like playing both equally. When you play a good guy, there are more roles and you become more well-liked. But, it is also nice to play bad guys because you have to rationalize bad and bizarre behavior and it is more of a challenge.
(about filming film in H.D.)
Michael: It's really easy to reset... something happens psychologically when you cut on the film. A scene kind of breaks down, and make up people rush in, the wardrobe people rush in, a guy wants to re-light, the actors got a question and all that sort of stuff. But if you just keep it rolling and you just keep doing it over and over, you just get so many shots that way.
(when asked if he intentionally seeks out action filled roles)
Michael: No I don't really seek out anything. I mean I'm always looking for a good role. What makes an actor good is the roles that he plays. If you've got a great role that's the thing that's the most fun to work on.
