"I can't say enough about her," Cooper, 35, gushed to Entertainment Tonight about his Case 39 costar, whom he first met while filming the supernatural thriller. "I just love her. I [loved] coming to work. I love acting with her. I can learn so much from her."
Echoing Cooper's sentiments, Zellweger, 41, who recently moved into a newly renovated $4.7 million home with her beau, told ET, "[Bradley]'s a great, great actor. I just got so excited, not believing that I was going to go to work with him."
