During Larry Talbot's first transformation into the Wolf Man, he goes from wearing light-colored night clothes to a dark shirt and pants. When he awakens the next morning, he's back wearing the pajamas.
In the long shot of Frankenstein's monster carrying Elsa up the stairs, her long flowing gown hangs down to his feet; to avoid stepping on it, he clearly has to take wide strides up the steps. Then there is a cut to the monster as he reaches the top of the stairs, and here Elsa's gown is completely wrapped around her body.
When the moon rises to transform Talbot in the hospital, moonlight is shown moving across the floor then up the wall to his bed. A rising moon would cast its light first on the wall, then move down the wall to the floor as the moon rose above the horizon.
After Lawrence Talbot and Maleva are told to leave Vasaria, Maleva is arrested when the townspeople are hunting for the wolf that killed the innkeeper's daughter. A few scenes later, Talbot is back in town at a public celebration socializing with the mayor and others. The townspeople do not seem to take much notice that the strange man from earlier is back and make no attempt to arrest him. Also, somewhere between his encounter with the monster and this point in the story, Talbot acquires a suit. It is never explained where or how he got this suit, though the film script stated that Talbot found some of Dr. Frankenstein's clothing and money in the ruins of the sanitarium.
After Frankenstein's Monster drops the Baroness and starts to fight with the Wolf Man, the two take a tumble down the stairs. They bump into a piece of the wall near the bottom of the stairs, which can be seen to actually be made of rubber.
