I never understood why Hollywood insists on using A list actors to do voice acting for animated features. Most of the time it's not even apparent who's performing and I hardly find it a draw that some big name is listed on the billboard. Dis we really need Chris Pratt and Jack Black to do the voices for the Super Mario movie? Especially when Chris Pratt is basically using his regular voice the whole time?
