If you needed representation and could only choose from one of the three most famous agents from HBO shows-Arliss Michaels of "Arliss," Ari Gold of "Entourage," or Jeff Greene of "Curb Your Enthusiasm"-who would you pick? Arliss might show you more money, Ari wouldn't let you miss any opportunities, but Jeff would certainly be the one you'd want to hang out with most. (It helps if you're already rich and don't look for much work anyway!) Loyal as a dog, but not sycophantic; mercilessly henpecked but a loving father; and best of all-when Jeff Greene takes a client to lunch it actually involves eating! He'll lie to your wife for you, he'll mend relations with the friends and family you insult, and he'll insist (loudly!) that HBO pays for the porn you watched in your hotel room. Jeff Garlin brings to the role much of his own lust for life, years of standup and improv experience (including stints at Chicago's Second City), and a passion for the same classic sit-coms that Larry David admires. Garlin recently finished directing his first feature ("I Want Someone to Eat Cheese With") and talks with us here about phones, Jack Benny and sponge cake.
