LOS ANGELES, April 4 (UPI) -- Johnny Knoxville will provide the voice for Leonardo in the upcoming Teenage Mutant Ninja Turtles movie.
The 43-year-old Jackass star will provide the voice for the half-shell leader to accompany Pete Ploszek's physical portrayal of the character. Ploszek performed Leonardo's movements for the movie, and turtle effects were later added with CGI.
