I wouldn't use a cinematic example in this debate, because I think showing and telling mean somewhat different things there; the only telling that can happen in a visual medium is through dialogue, but in fiction it can also happen through exposition.
But it's definitely through that not everything deserves to be shown, and in the right circumstances, a judicious bit of telling can be more effective. To show everything would take forever, so you spend that on the things that merit it: important bits of character (especially to avoid situations where we get told one thing and shown another, or situations where you both show and tell, and we get irritated at the redundancy), or important bits of action (like climactic battles). Somebody's got a name for this technique -- it's something and leaping, I think, but I forget -- basically, deciding what's important enough to show, and what you can swiftly gloss over with a bit of telling. A bit only; it's the lengthy stuff that's really a problem.
