Jonah Hill has given out his cell phone number and is taking calls from fans as part of a promotional stunt for his new movie.

The funnyman stars in "The Sitter" as a college student who takes on a babysitting job, and promotional posters for the film feature a picture of Hill, along with a telephone number and the message, "Need a sitter?"

The number goes through to a cell phone carried by Hill, featuring a voicemail message left by the actor in character.

He occasionally picks up the phone and talks to callers, while he has also received 50,000 voicemails and 7,000 text messages, according to the New York Post's Page Six gossip column.
