Broadway Rose is a 1922 American silent romantic drama film released by Metro Pictures and directed by Robert Z. Leonard. It stars Leonard's then-wife Mae Murray and Monte Blue. The film is based on an original story by Edmund Goulding written for star Murray, and was produced by Leonard's and Murray's production company Tiffany Pictures.
Tiffany Pictures started making films in 1923.
As the agent says that the film was made by Tiffany Pictures in 1922, then they cannot have started making films in 1923 as this was later than when they made Broadway Rose. I think that it was difficult for the system because there were no negatives in the statement.
