According to SFGate.com actress Amanda Seyfried had insulted Leo.

Amanda Seyfried was horrified after she accidentally “insulted” Leonardo DiCaprio by asking him to play her father in a new movie.

The “Titanic” star is producing Seyfried’s upcoming film “Red Riding Hood,” and when the actress met the star to talk about the movie she attempted to persuade him to take an on screen role.

But DiCaprio was unimpressed when he realized Seyfried wasn’t asking him to play her love interest – she wanted him for the part of her character’s father.
She tells Britain’s Daily Mirror, “Unfortunately, he’s not in it. I asked him if he would play my dad but he got insulted. He said, ‘I don’t do male leads in love stories anymore.’
“And I said, ‘I wasn’t talking about the male leads, I was talking about my dad! You’re what, 35? Age yourself up a bit!’”
