In the scene where Bob just got home from the bar when his "Irish uncle" turned off the TV and Ritchie was on American Bandstand...He goes down to Ritchie's room and starts tearing down all his drawings.. you can plainly see that the wall is made out of brick.. but in this case he pounds so hard on the wall that it sort of moves like if it were cardboard.. either this is a mistake that could've been avoided if they had used a REAL brick wall.. OR.. Bob is so strong in fact that he can bend Brick...????
