"The term 'serious actor' is kind of an oxymoron, isn't it? Like 'Republican party' or 'airplane food.'"

In this quote, Johnny Depp is making an amusing observation about the entertainment industry and politics. He is recommending that the term "major star" is inconsistent due to the fact that acting is frequently related to playfulness and pretending, while being severe is normally viewed as the opposite. Similarly, he compares the term to other apparently contradictory expressions, such as "Republican celebration" and "airplane food." By using these examples, Depp is highlighting the absurdity of labeling something as serious when it may not necessarily fit that description. In general, the quote showcases Depp's wit and his ability to satirize societal standards and expectations.
