NEW YORK - First-time movie producer and mom-to-be Chelsea Clinton has premiered a short film at the Tribeca Film Festival.

Clinton is the executive producer of the short "Of Many," a documentary about the friendship of two religious leaders at New York University. One is rabbi, the other is an imam. Clinton was previously an assistant vice provost at NYU.

The 34-minute film made its Tribeca debut Thursday night. The screening was attended by the 34-year-old Clinton and her father, former President Bill Clinton.

Chelsea Clinton announced Thursday that she and her husband, Marc Mezvinksy, are expecting their first child this fall.
