Besides being homophobic, Mr. Hassan is also apparently jealous of Mr. Craig's superior skills as an actor. 

Mr. Hassan can get him and his son a few things to make life easier:  #1- A tee-shirt with the new "Some People Are Gay -- Get Over It" slogan now being used in the UK and #2 a personal trimmer for himself (being used for years now the world over.)  Can you say "Uni-brow"? 

 Don't trouble yourself Doctor -- I'm a celebrity, I'll write my own prescription.

Actors do win awards sometimes for playing gay (Tom Hanks for example), but of course it's conditional on the performance and on the Academy voters not just on playing gay for obvious reasons.  However, I recall an interview where Tom Hanks was asked about explaining to his kids and their peers his playing gay.  Hanks's answer was that he would tell them: "Daddy's an actor." 

Will Smith openly admits that Six Degrees of Separation was critical to his subsequent career success because it helped him break free from his hip-hop boy image from Fresh Prince of Bellaire.

Some actors, however, never want to play roles that are outside their preferred self-image.  Hassan seems to have felt the need in his homophobic stint to assert his own "manhood" twice, both in himself and in making it clear that his son is an athelete (manly fathers produce manly sons).  Clearly he worries a lot about his "manhood".

Instead of worrying about how your son would get picked on by his teammates if you took a homosexual role, you should start worrying about him getting needled about his dad being an idiot. That has to be one of the stupidest quotes I've heard from an actor. "They can keep their Oscar and I'll keep my virginity." Huh?  Are you that insecure about yourself and the image you're conveying to your son and his "friends" that you'd say something that idiotic?  Way to go, dad...
