George Nader acted in many movies during the 50s to 70s period. This period is also called a period of change in Hollywood cinema as directors were becoming more liberal and ready to take chances. In fact, Nader’s first blockbuster film was a 3D special in which he played the starring role.
‘Robot Monster’ (https://en.wikipedia.org/wiki/Robot_Monster) was directed by Phil Tucker in a total of 4 days on a budget of $16,000. The film went on to make millions on the box office and quite possibly the highest Nader ever had. Because of this film’s success Nader was picked up by Universal and cast alongside A-grade actors such as Rock Hudson, Jeff Chandler and Tony Curtis.
