As Joan tears the closet apart in the "No wire hangers!" scene, a wide shot shows her throwing blankets off the first shelf as she screams "All of this is coming out! Out! Out!..."
In the next shot, the blankets have returned, neatly folded, on the shelf.
When she goes upstairs to tell Tina the good news about her part in an LB Mayer movie, she catches Tina making fun of her. When she goes to cut Tina's hair she cuts all of it off in the first shot then new hair suddenly grows back like a chia pet when the camera pans in and Joan is going crazy cutting and cutting saying "you spoiled it just like I spoiled you who who!!!!"
In the chopping of the rose bushes scene, she keeps yelling things such as "Box office poison", but when you look closely she is only mumbling. Not yelling or saying what is heard.
In the rose garden scene, when she chops down the tree, it makes a big THUD like it's an oak or something!!!
