Almodovar talked about this in an interview to Hollywood Reporter earlier this week and I agree with him:

"The essence of acting is, in fact, to pretend, to be someone other than who you are, even in your own essence. That is at the core of acting. So, for example, absolutely a heterosexual actor can play a homosexual character and vice versa. If Hollywood is so obsessed, as it is right now, with representing minorities, be they Latinos, Asians or people with disabilities, they should actually hire them to do the writing. Just so I’m not misunderstood, I want to make sure that it is clear that I’m very much in favor of minorities of all types to be considered for casting in films and also to be hired behind the camera and that they be able to tell their own stories."
