"If Chevy Chase had not been an actor, he might have been a very popular guy in advertising or whatever field he would have gone into, because of his charisma"

In this quote, Harold Ramis is suggesting that Chevy Chase possesses a natural appeal and likability that would have made him successful in any career he chose. Ramis, who dealt with Chase on a number of films, thinks that if Chase had actually not pursued acting, he would have mastered fields such as advertising due to his charisma. This suggests that Chase's charm is not restricted to the entertainment industry, but rather a quality that would have made him stand apart and be well-liked in any occupation. Ramis's words also recommend that Chase's success as a star is not exclusively based upon his skill, but also on his inherent appeal and charm.
