Jeremy Sisto recalls how he almost read co-star Sam Waterston's lines for lead character Jack McCoy at his original "Law & Order" audition before realizing he had prepared the wrong role. (Whoops!)
"I get there and Sam Waterston's in the [room] with me as we're … starting to read the scenes and he's reading my lines. I had prepared the wrong character — the lead of the show," Jeremy says. "So I had to pretend that I didn't do that and learn my lines quickly."
