Of the four "Seinfeld" leads, Jason Alexander has worked the most since ending the show. The actor has appeared on nearly two dozen television series, including "Star Trek Voyager," "Malcolm in the Middle," "Criminal Minds" and "Curb Your Enthusiasm." Alexander, now 55 (and sporting more hair than he did in the '90s), recently appeared in the series "Big Time in Hollywood, FL." —XFINITY Entertainment Staff (Photo by Alberto E.
