I found this out in an extensive Movie encyclopedia that I own, and I also checked online to verify. I found something out about the movies Star Trek II and III (with the old 60's Trek lineup). The actor that played Admiral Kirk's adult son David (his name was Merritt Butrick), died in 1989 at the age of 29. He died of AIDS. I just thought this was interesting as while I am by no means a huge Trekkie, I do think that #2 was an especially entertaining movie. Not to mention to die that young is a really terrible thing.
