Jude Law's 'Sherlock Holmes' costume felt like a "razor blade" against his throat.
The British actor - who portrays the title character's sidekick Watson in the Guy Ritchie blockbuster - was left uncomfortable and hungry while wearing the old-fashioned attire because the restricting collar meant it was difficult for him to swallow his lunch.
He explained: "I had to wear this terribly stiff, tight collar as part of my costume which was just horrible. On the first day I actually tried staying in character and wearing it to lunch. It was like trying to swallow sushi with a razor blade around my neck!"
The 'Alfie' star recently admitted he thought he was "insane" to sign up to the movie.
He only agreed to the part when he heard Robert Downey Jr. would be portraying the famous fictional detective.
He said: "I met Robert Downey Jr. and wanted to work with him and so I said I'd do 'Sherlock Holmes'. Two days later I thought, 'What am I doing? This is insane because is it really what I want to do?'
"Luckily, it evolved into a wonderful experience."
