"(Bryan) writes the way he acts - with fierce commitment, intelligence and humour,'' she said.
Breaking Bad officially concluded last year after airing for five seasons.
Cranston previously admitted he was slightly disturbed when he watched the finale in a Hollywood cemetery with co-star Aaron Paul and 4,000 excited fans.
"It was really emotional for me, watching myself die among the headstones. It was a beautiful night. Everyone was on lawn chairs. It was like a really big, morbid picnic,'' he told Empire magazine.
Following a successful string of TV appearances, Cranston is back to making feature films.
He will next be seen in Godzilla alongside Elizabeth Olsen, Aaron Taylor-Johnson and Juliette Binoche.
