"I know, because I tried all sorts of ways of being in character, and the best way is to be totally straight"

This quote by Tommy Chong speaks to the value of authenticity in efficiency. He is suggesting that the best way to be in character is to be completely straight, meaning to be authentic and sincere in one's portrayal. This is likely a recommendation to the concept that the very best performances come from actors who have the ability to draw on their own experiences and emotions to bring a character to life. By being completely straight, an actor can be more in tune with the character they are playing and can create a more credible and appealing efficiency. This quote also speaks to the concept that the very best efficiencies come from stars who are able to be susceptible and sincere in their representation. By being absolutely straight, a star can develop a more powerful and significant efficiency.
