Ryan Reynolds is the cover boy for the most recent issue of Details magazine, and Sandy is quoted on his interview:

Sandra Bullock says her longtime friend and costar has a complexity beyond the friendly face that draws an audience in: “It makes you want to watch more of him to figure it out. As his friend, any dark secrets that I may or may not know are forever safe with me. Unless he doesn’t do something I want him to do, like babysitting. When that day comes, I’ll be sure to hold a press conference.” The rest of his success she credits to his comic timing, height, and Canadian-ness. “He constantly talks of the healing powers of maple syrup,” Bullock says. “I don’t know if that’s a Canadian trait, but it’s always uncomfortable when it comes up.“
