He explained: "Our great make-up artist Lucy Cain suggested a prosthetic nose. It was quite an understated prosthetic which covered only the tip of my nose but cleverly bridged the gap between us in a subtle way. We also experimented with wigs briefly but I ultimately had time to grow my hair out a little longer."

The actor also spoke to Tom about the role, saying: "We met a few times before we started shooting. Partly to work out make-up and costume decisions but also to discuss the character too. Tom was incredibly kind with his advice and sharing his thoughts for the character, which were invaluable, and that continued throughout filming as well.

"I even remember one day we were filming our wedding scenes and both Gina and I were feeling nervous. Tom had finished filming for the day but he went home, picked up a bottle of champagne for us and gave us a little glass to calm our nerves. Then he stuck around while we filmed the scene and gave us some really helpful notes and ideas."
