Keri Lynn Pratt Hot Style Pictures: World's Greatest Dad Premiere Red Carpet Photos

Actress Keri Lynn Pratt arrives on the red carpet at the Los Angeles premiere of "World's Greatest Dad" held at the Landmark Theater on August 13, 2009 in Los Angeles, California.

Lance Clayton (Robin Williams) is a man who has learned to settle. He dreamed of being a rich and famous writer, but has only managed to make it as a high school poetry teacher. His only son Kyle is an insufferable jackass who won't give his father the time of day. He is dating Claire, the school's adorable art teacher, but she doesn't want to get serious — or even acknowledge publicly that they are dating. Then, in the wake of a freak accident, Lance suffers the worst tragedy and greatest opportunity of his life. He is suddenly faced with the possibility of all the fame, fortune and popularity he ever dreamed of, if he can only live with the knowledge of how he got there.

"World's Greatest Dad" arrives in theaters on August 21.
