ABCD (Spoiler)
Did you notice the first names of the characters ? Manglehorn's first name is Angelo with an A, his ex-wife is Beatrice with a B, his lost love is Clara with a C, and his to be / current girlfriend is Dawn with... Well, you know where this is going.
You may think that all this is a coincidence, but the ex-wife first name was brought in the father-son conversation with almost no reason. The first names of the Pacino and Hunter were revealed at the very end of the movie.
And if you still have some doubts, remember the ABCD that we can see on the arm of the tractor ditching Manglehorn's boat.
I don't know if it's just a sort of easter egg, or is there some hidden meaning, but I felt quite puzzled after seeing the movie.
Any thoughts ?
