Hi Del,
I think Jake was talking (on and on and on) about something other than just the general overall nervousness of acting.
He was, at every turn, asserting his offscreen heterosexuality (if that even turns out to be the case we are not yet sure), distancing himself from the characters by alternately claiming they were straight guys who just happened to fall in love, etc., combined with his talk (and talk) about his own prejudices, etc.
Why not just do like Gael Garcia Bernal, Antonio Banderas, Stephane Rideau and Javier Bardem (who said he personally had to find a way to be attracted to his costars in Before Night Falls)? They all praised the material, their director and costars as attractive, said the experiences were about learning and growing as people, and certainly pleasant.
Jake's push-pull of the press, material and his own odd takes on the characters and his sexuality really turned me off. And I like Jake, so I have no bias against him. I found his remarks increasingly bizarre and sort of offensive, though he didn't intend them as such.
Just my twenty cents or so.
