William Shatner as Harry Mudd. Or would that be too distracting?
Wow. That would actually be kind of brilliant.
But in all seriousness, the only standards I have for the next Trek movie are:
(1) A good story that is compelling and entertaining, and
(2) A bit less blatant fan service.
And as long as (1) is mostly there, they can probably get away with (2) again, as far as I'm concerned.
