What did Sam Elliot say?
The biggest missed opportunity can actually be found in Tom Hardy.

Spider-Man Homecoming is a market researcher's dream, the kind of thing that can only come from 6 writers, a director-for-hire, and 2 studios bending over backwards to manage the feat of making the 3rd big screen Spider-Man incarnation without pissing anyone off.
