Apatow is to be the host of "A Night of Funny People" at the Orpheum, during which Sandler, Rogen, Hill and Ansari are to perform live as their characters from the film.

Oswalt and other surprise special guests are to be included in the lineup, as well.

Tickets are $20 and are to go on sale through Ticketmaster Friday. Audience members must be over the age of 18.

Proceeds from the night will benefit the National Multiple Sclerosis Society and 826LA, Universal said in a news release.

"Funny People" is scheduled to open in U.S. theaters July 31.
