"Beware the Ides of March..." because March 15 is also the day in 1973 that George McFly was killed by Biff Tannen in one of the series' darkest timelines of Back to the Future. Jeffrey Weissman, who played George in Back to the Future II and III, talks about playing Marty McFly's father (and other stories from the film's set); the unreduced story of how he got the role; lessons learned from roles in Clint Eastwood's Pale Rider and Twilight Zone: The Movie; the importance of actor diversification; subtle and nuanced performances in The Show Must Go Online; and a return to his Shakespearean and comedy roots.
