VIDEO : Pamela Anderson to Appear in New 'Baywatch' Movie

In an unexpected twist on Thursday, Dwayne 'The Rock' Johnson revealed the addition of one more cast member for the upcoming 'Baywatch' movie: Pamela Anderson! In a post on Instagram, Johnson wrote, "A pleasure to welcome Pamela Anderson to our #BAYWATCH cast. We couldn't have made this movie without you. Welcome home." Anderson's casting in the film might come as a surprise to some as she previously told E! News that she didn't even think a movie about the hit show would ever make it to the big screen.
