Some of the celebrities and high-powered executives who gathered at Conan O’Brien’s annual holiday party on Dec. 13 are likely to be called to testify in the first-degree murder trial of Nick Reiner, especially if he pleads not guilty by reason of insanity in the fatal stabbing of his parents, legendary director Rob Reiner and Michele Reiner.

While Conan O'Brien gives a surprising performance in 'If I Had Legs I'd Kick You', don't expect him to take on anymore dramatic roles.

Arnold Schwarzenegger has always put his body on the line for his roles, but the set of Conan the Barbarian got a little scary.
