Brendan Gleeson has told RTÉ Entertainment that several takes were needed to perfect scenes in Paddington 2, and admits it was challenging trying to "keep the energy up" during filming.
The 62-year-old actor, who plays Knuckles McGinty in Paul King's sequel to Paddington, says he found the technical side of the new animated adventure comedy to be "tough enough".
"It's quite a technical thing, so trying to keep the kind of madness in it, while maintaining the discipline of the technical side of challenges, it was tough enough.
"There were a lot of takes and we had to try and keep the energy up, and the frantic nature of the storytelling, and keep it in the right place," Gleeson added.
The Dublin star said he enjoyed working on a lighter movie after a string of darker roles (Assassin's Creed; In the Heart of the Sea; Live by Night), and admits it's important to "mix it up".
"It is good to mix it up a little bit. If everything gets on the one colour spectrum, it gets a bit dull," he said.
