Great chemistry. They starred in 5 movies together. The first was a decade ago with The Prefect Score although their characters didn't cross paths that much. But according to them, the one scene they had was memorable.
The actors finally got their chance to be an onscreen pair via the chicklit film The Nanny Diaries (2007). After those projects, they work together in Marvels and gave their pair another try in the second installment of Captain America.
