She tells People.com, “I am making the first 3-D beach comedy about a shark that attacks a small beach town and I save the day with my 3-D boobs. I’m now finally free to start my career and my new life as a female mogul in Hollywood!"

Montag is eyeing an all-star cast for her debut movie project: “I’ve even written a role for Dolly Parton to play the town mayor!”
