Following his amazing performance in "Rocky", critic Roger Ebert had once said Stallone could become the next Marlon Brando, although he never received the same critical praise achieved with "Rocky". Stallone did, however, go on to receive much approval for his role in the crime drama "Cop Land" (1997) in which he starred alongside Robert De Niro and Ray Liotta. The movie was only a small success at the box office. His performance led him to win the Stockholm International movie Festival Best Actor Award. In 1998 he did voice-over work for the computer-animated movie "Antz," which made over $90 million domestically.
