Today's sopa viewers may be savvier than ever, but Nolan North thinks some people still have trouble distinguishing actors from the characters they play. Consider the reaction two of North's neighbors had when they caught him hanging out after-hours with his on-screen rival, Mitchell Longley (Matt). "Matt and Chris are always at each others' throats," says North. "But I actually consider Mitch a very good friend -- he's a great guy, and we have a good time together." In May, North invited his pal over to his apartment to catch the series finale of SEINFELD. A neighboring couple spotted the two hanging out and did a major double take. "Mitch started laughing," North recalls with a chuckle. "They probably watch the show and were shocked to see us laughing and having a good time."
