London, Jan 19 : American actor Robert Downey Jr is angry with director Guy Ritchie after he was made to wear four-inch platforms in his shoes during the filming of a new movie.

Downey Jr and Ritchie had become friends while filming Sherlock Holmes, but now their friendship is in peril because of the shoes.

The Iron Man star plays the role of the detective in the movie with Jude Law playing as Dr Watson.

Ritchie made him wear the shoes as he felt the two should be of the same height.
