it's like needlepoint -- too much effort for the eventual payoff

Today I spent thirteen hours in a hot, itchy wig, playing a flapper in a speakeasy in a short film. I have only now come to realize what kind of effort goes into producing movies. Thirteen hours for eight minutes? If the entire film industry just stopped producing films and turned that quantity of effort towards solving world hunger ... well, we'd be really bored at the theater.
