Ben Stiller was on hand to greet a sold-out crowd attending a "Zoolander" screening at Hollywood Cemetery Saturday night — and he was joined by "Severance" star Tramell Tillman, who showed up with the University of Southern California's marching band in tow.

Ben Stiller and Tramell Tillman made a surprise appearance at a Zoolander screening hosted by Cinespia in Hollywood on August 16. Footage captured by Samuel Granillo shows Stiller addressing the crowd in character as Derek Zoolander.
