Factual error: No actor is going to secure a recurring speaking role in a soap opera unless a comprehensive insurance policy has been secured. (This applies to feature films, too.) This will inevitably involve a medical examination. Mr Dorsey's plans are going to become dreadfully unstuck the minute he drops his y-fronts in the doctor's surgery. (No, he can't find a compliant or bribeable doctor - the insurance company will always use their own people.)
Continuity mistake: When Dustin Hoffman (dressed as Dorothy) goes to babysit for Jessica Lange he takes a bunch of flowers as a present. Jessica Lange takes them from him and throws them on the kitchen table. Then she walks into the kitchen (shot from different angle) still holding the flowers and throws them on the table (again).
Plot hole: "Dorothy Michaels" does not exist, but suddenly becomes famous. It is simply not feasible that nobody looks into her background! Not one single print or television reporter is interested in her life story? Nobody has ever wondered where she came from, has checked into what other roles she had played, or has expressed interest in her personal life? That's impossible.
Plot hole: Since "Dorothy Michaels" does not exist, she will not have a Social Security number. Even with her agent acting as a go-between, the television production company, her employers, would have to have this for their records. Supplying a false Social Security number is a very serious offense (and is instantly detectable), as is employing someone without one.
Continuity mistake: When Hoffman accompanies Teri Garr to the audition for the role he later gets, his hair is obviously shorter (ears showing, etc.) than in the rest of the film.
Continuity mistake: In the scene just before Michael admits his infidelity to Sandy, he lays his wig down on the kitchen table. Later, the wig disappears from the table though neither Michael nor Jeff had removed it.
Plot hole: Michael Dorsey is a jobbing actor working as a kitchen hand, and his flatmate Geoff is an aspiring writer trying to raise the capital to have his latest play on stage - yet they can afford a huge, open plan apartment in New York City. The rent on that apartment would easily exceed their combined income from their low-paying jobs. There is no indication that they are independently wealthy - why would they need Dorsey's fees from the soap opera to stage Geoff's play if they were?
Continuity mistake: During the conversation between Dustin Hoffman and Sidney Pollack in the beginning, Sidney points to the table with his left hand and says "I'm supposed to field offers" but in the next angle, he points with his right hand.
Continuity mistake: For the first few scenes of Tootsie, Dustin Hoffman looks like he had his eyebrows plucked. Maybe they filmed those scenes later.
Continuity mistake: When Terri Garrett comes to the apartment and Michael is in makeup he leaves his wig, earrings, shoes and purse in the dining room. Bill Murray picks up the shoes and purse, but not the wig or earrings. He places those items in the bedroom, however when he returns the wig is gone, and only the earrings remain, which he disposes of in a jar.
Continuity mistake: When Michael says he finds the blonde actress on the balcony interesting and wants to make love to her, and she splashes her drink in his face, the drink gets on the guy behind Michael. When Michael wipes his face off the man's coat, his coat is dry again.
Continuity mistake: After the first day of shooting, Jeff is seating next to a phone holding a pencil, which disappears/ reappears randomly in his hand between shots.
Continuity mistake: During Michael's first discussion with his agent about not finding a job, the agent puts his pen on the notepad in front. The pen disappears/appears randomly depending on the angle.
Continuity mistake: At the dinner table when everyone's at the house in upstate NY, the piano in the background is a console model but later as Tootsie plays the piano, it's become an old upright.
Continuity mistake: In the scene where Michael is about to tell Sandy that he loves someone else the clock behind them is about 12:30. About a minute later when she screams the clock behind them is now after 1:00.
Answer: No I believe that's from the movie.
