As expressed by Rob Prochnow the filmer, Ben didn't take to the streets to film his part half-assed. He had pre-planned spots months in advance and as soon as the winter set in was setting up spots in advance to hit the following day to really make the most of the time they had to get clips. Though with injuries and other obligations the winter ran short fast, and so it came down to shooting about 60% of his part in the final 3 weeks of the winter. It's fair to say 'Efforts' were made for this one.
