Tom Hanks as Walt Disney
Tom Hanks says that it was incredibly important to capture the look of Walt Disney in Saving Mr Banks.
Hanks takes on the role of Disney in the new film, that follows his quest to turn the novel Mary Poppins into a musical movie.
And the Oscar winning actor reveals that everyone worked incredibly hard to get the moustache looking just right.
Speaking to Access Hollywood he said: I don't have the same facial structure as Mr Disney had, so the moustache had to have a particular angle to it, it couldn't be too wide, but it couldn't be too narrow.
"It had to have a certain amount of skin between the moustache and the bottom of my nose. The creative team [had] close-up, blown-up like spy photographs of Walt Disney's face with arrows and measurements and graphics.
"Like a scale of hair-per-centimetre kind of thing. It was a very important moustache. It was the most analysed, discussed [moustache], short of getting memos from upstairs in Disney. This was the most important moustache in the history of mankind!"
Saving Mr Banks sees Hanks team up with Emma Thompson for the first time as she takes on the role of author P.L. Travers.
An all star cast has been assembled as Hanks and Thompson are joined by Colin Farrell, Paul Giamatti, Jason Schwartzman and Ruth Wilson.
Saving Mr Banks will be the second movie in quick succession for Hanks, having received huge praise for his performance in Captain Phillips.
Saving Mr Banks is released 29th November.
