to help the kid actors on Peter and Wendy believe in his character's meanness, Jude Law stayed in character the entire production (well done, not easy) but after the film wrapped, he got out of costume, and arrived on set driving an ice cream truck to make it up to them (and ditch the character in their eyes)

“David Lowery had the idea of really trying to encourage them not to see me when I wasn’t Hook,” Law said. “So I just stayed as Hook the whole time, which was an opportunity just to be really scary and mean. And, yeah, a lot of the reactions you see in the film are their reactions to me for the first time, or as the man himself, you know?”

Law recently told Collider about his version of Captain Hook: “I wanted him to be sad, I wanted him to be scarred and gnarly and disgusting and scary, and funny too. Like an overheate, angry dad or uncle who, from a kid’s perspective, is just really pathetic and loud.”

When filming wrapped and Law was ready to reveal his actual self to his young co-stars, he decided ice cream might ease the transition.

“They met Jude at the end,” Law said. “And I did what every adult should do to bribe children. I hired an ice cream van and I drove it on-site and gave out ice cream. Nothing like chocolate ice cream to persuade a child you’re alright.”
