Thank you for your help.

"What does this sentence mean?" You're being specific about "this" sentence (which the reader expects to be the sentence you quote next), not talking about "the" sentence, which the reader would expect to already be in context (but it isn't). The string of letters "content" can mean "at peace, satisfied, happy" (like it does here), or it can mean "something that's contained inside some container, or conveyed by some medium." A film can't be "content", since a film has no emotions. The producers of the film can be content, though. So your sentence means "the film's producers are happy/satisfied/prepared to use him for his ability to be humorous." One reason that this sentence is particularly wrong-headed, is that movies are examples of "content", using the opposite meaning to the meaning intended here.
