I watched the movie again just last week, and thought the same thing. I'm pretty sure to OP is not slamming Dooley, but if you watch, it's hard not to see Dooley in that actor. They look very similar, have similar mannerism, and at least in the movie, they have the same accent. Even my wife pointed it out how much that guy reminded her of Dooley.
Again, not an indictment of Dooley, just a simple observation.
