Watching Chris Evans in his new movie Gifted, one can't help to think of what he'll be like when he has his own kids.

In the Fox Searchlight film, the Captain America star plays a boat mechanic raising his six-year-old math prodigy niece (Mckenna Grace) when his overbearing mother (Sherlock's Lindsay Duncan) takes him to court to gain custody of the young child.

At one point, Evans breaks down in tears.

"Crying on cue is a tough thing to do, but I tell you what there is no better catalyst than this little nugget over here," Evans says as he looks at his 10-year-old co-star. "She is so good and so honest. Those tears start rolling, you would have to be pretty heartless to not get emotional."
