Late news, but I came across this interview given by Demián Bichir – who worked with Sandra in The Heat – to Where Magazine where he talks a little about her and that’s always good to read:
What was it like working with two of the funniest ladies in Hollywood for The Heat?
There’s a lot of improv going on. Most of my scenes were with Sandra, and I remember laughing in tears between takes. She’s really funny, and sexy and beautiful and a wonderful actor. It had been a long time since I laughed that hard.
I hear you taught her Spanish.
I’m not kidding, I was her Spanish coach! She had to talk in Spanish a bit [during the movie]. Her Spanish is not only great [once] she learned it, but her accent is great, too. I mean, she could be Mexican!
