became a fan... of the film, that is

[Ostap]

In the documentary "Back in Time," Adam F. Goldberg, creator of "The Goldbergs" TV show, recalled that his mother came back from the movie theater in 1985 and told him, "I just saw this amazing movie called Back to the Future. It's about a boy who goes back and falls in love with his mom." Her review immediately turned off the younger Goldberg for obvious reasons — although he later came around and became a fan... of the film, that is!

Hello everyone! When the speaker said "became a fan", and right after that clarified himself, it's clear from the tone of voice that "a fan" sounded ambiguous. Does it mean (it was probably just a joke, but still) that it could be understood as if Goldberg became a "fan (lover) of his mother"?

No. In my opinion there is no possibility of making that mistake.

What was the point of adding that piece at the end then?

Now you're asking me to be a mind reader. They were clearly talking about the movie, Back to the Future.

It's not mind-reading, it's logic. If he had ended the sentence with "... came around and became a fan." -- there would be no questions. But the fact of adding "of the film, that is!" makes it clear he deliberately made the previous part sound ambiguous for the sake of a joke.

It may be a bit of a joke, but that doesn't mean there's any ambiguity.

Yes. It's a weak joke.

It's a joke. He's not a fan of romancing his mother.

Not a fan/lover of his mother per se, but a joke about not falling in love with his mother - aka an Oedipus complex.
