Novak has decided to flex his acting chops and join the all-star cast of the Expendables 2. Fortunately, Novak won't have invest too much time training for his role because he is playing.....himself! He was invited by co-producer Avi Lerner to have a small cameo in the film opposite Sylvester Stallone and he has already shot his scenes during a recent trip to Bulgaria.
