"I think a lot of Magnum was me"

Tom Selleck's quote suggests that he related to the character of Magnum, the private detective he portrayed in the television series Magnum, P.I. This might mean that he felt a strong connection to the character, or that he was able to draw on his own experiences to bring the character to life. It might also indicate that he was able to connect to the character's struggles and triumphs, or that he had the ability to bring his own character to the function. It could also indicate that he was able to make use of his own life experiences to inform the character's decisions and actions. Whatever the case, it is clear that Tom Selleck felt a strong connection to the character of Magnum, and that he was able to bring a great deal of himself to the role.
