"There's a fine line between the Method actor and the schizophrenic"

The quote recommends that actors who take a Method technique to their craft might become so consumed by their duties that they wind up showing similar habits to that of individuals with schizophrenia. This might suggest that, while Method performing can be a really efficient method, it can also be possibly hazardous if not exercised responsibly. Eventually, it works as a cautionary tip concerning the power and possible mistakes of engaging oneself too fully right into a character.
