Michael Reid MacKay -- Summer Dreams: The Story of the Beach Boys (1990) Dennis Wilson's (and the Beach Boys') involvement with Manson is well-documented, which just goes to prove even rock stars can be prone to acts of questionable judgment. Charlie's appearance is at about the three-minute mark in the clip. I tell you that because you may have a hard time distinguishing him from the fake bearded Brian Wilson (Greg Kean) later on.
Jeremy Davies -- Helter Skelter (2004) What the...? They made *two* versions of Vincent Bugliosi's Manson trial book? You know, I'm against remakes as a matter of course, but if the recent news is true that a sizable number of people were unaware the Titanic was an actual boat that actually sank, maybe it's a good idea to make a new version every 30 years or so just to ensure more legions of Americans don't make idiots of themselves on Twitter.
Oh, and Davies also played the weaselly Upham in Saving Private Ryan. That guy was like the proto-Manson.
