This Rocky t-shirt shows Dolph Lundgren and Sylvester Stallone sparring in preparation for their epic boxing match as Ivan Drago and Rocky Balboa in the 1985 blockbuster Rocky IV. To make their boxing match look realistic, Dolph Lundgren and Sylvester Stallone practiced their fight before the cameras rolled. Stallone once told Lundgren to really try to knock him out. Lundgren went into "I Must Break You" mode, and Stallone was sent to a hospital for five days. It paid off because Rocky IV is one of the most popular sports movies of all time! For any fan of one of the greatest chapters in the Rocky franchise, this Rocky IV Ivan Drago Vs Rocky t-shirt is a must have!
