Teaching Mrs. Tingle (1999)

Plot hole: Mrs. Tingle was tied to bed for longer time, fed by her students, but what about going to toilet within this period?

Principal Potter: I was thinking.
Mrs. Tingle: No, don't do that Mr. Potter, we still prefer that bristling wind effect you have on us.

Trivia: Helen Mirren has given different reasons for taking the part of Mrs. Tingle. She was reportedly intrigued by the devilish role because it was unlike anything else she had ever played, and she enjoyed how the film showed the turbulence of adolescence. She also quipped that she got paid a "shitload of money" and that it was an easy job because she spend most of the film tied to a bed in a comfy nightgown making catty comments.
