It recently came out that Robert Deniro was originally cast to star in Tom Hanks iconic movie 'Big'. Deniro dropped out of the movie a few weeks in and Tom Hanks was cast in the film that took his career to the next level. We decided we wanted to find out what it would have been like if Deniro had finished the film so we decided to have Mario act out one of the iconic scenes with Courtney. Check out the break below and let us know what you think! Mario pretty much nailed it! Hit us up @ONWithMario on twitter!
