Hugh LaurieEdit

Hugh Laurie was one of the worst connected actors on the show. Although he has other minor connections, until 2011, the only two on-screen actors he has appeared with outside of the series were Scott Michael Campbell (in Flight of the Phoenix, when on location filming he made his breakthrough audition tape) and Leighton Meester (in The Oranges, where he plays a character who is obsessed with her). He finally has increased his total, largely due to his guest appearances on Veep:
