At five foot nine inches, Robert is hardly short - but director Guy Ritchie insisted that Robert's character be tall when standing next to the six foot one Jude. And Rob is hating it!
A source told The Sun that "Robert is stumbling around a lot and cursing Guy over the silly shoes."
Robert has reportedly been a bit of a diva on the Sherlock set so far, insisting crew fetch him hard-to-find items despite shooting in the middle of nowhere.
"Robert had one crew member running around like a headless chicken trying to find a straw," The Times quote a source as saying.
"The poor guy was stressing as they were in the middle of nowhere on an old dockyard, so there was hardly a store nearby."
Karma's a bitch, though - Robert has already copped an accidental punch by a stuntman which needed six stitches, and accidentally set his crotch on fire. Fireballs!
