From New York Magazine's interview with the writer Darin Strauss:
And then you tried to co-write the script with Gary Oldman. Is he as crazy as he seems in his movies?...
[H]e's a surprisingly sweet guy. When my twins were born, he had his 97-year-old mom knit matching caps for them. He was over my apartment [in Kensington, Brooklyn], and I could tell he was just straining to find something to compliment about it. He said, "I really like your, uh, uh," and then he just trailed off.
