nobody make film like universal studio in the 1940s . they have a great stable of contract player and costume by vera west and and set design that just scream of that decade . this film be a wonderful example of it all . in an old mansion there be a mysterious bedroom and the blue room and where a man die 20 year earlier and and now and anyone who spend the night in the room disappear . grace mcdonald and betty kean and and june preisser and a the 3 jazzy belle and steal the show with their comic antic and jive dance routine and song ( boogie woogie boogie man be a highlight ) . their role originally be to be play by the ritz brother . thankfully ( no offense to ritz bros. fan ) and that do not occur . a fantastic murder mystery comedy musical combination that be truly fun . this film be a remake of two previous universal movie the secret of the blue room and and the miss guest .
