Will Smith knows how to get a crowd going! The actor was filming in 11 degree temperatures in NYC with more than 1,000 extras. While they were waiting around to shoot a scene the actor found a way to take their minds off the super cold day. The Fresh Prince busted out Summertime to the crowd which sang along during the chorus. I know I would have been dancing along with the crowd as well.
