Steven Seagal, so old and tired that they barely even show him actually punching guys any more. He also slowly walks everywhere, maybe to prevent more embarrassing videos of him trying to run.
Given Mr. Segal's ego, I give it even odds they had to film the entire thing with him before quietly going back and filling in 90% of it with a double without telling him.
Where they even in the same room? Also, i didn't think time-syncing dialog was that hard/ expensive these days. Steven Seagal is the modern Coleman Francis.
The had to use a double. Steven Segal cannot hold back his true power enough to not kill a dude. The editor got three black eyes just from looking at the raw footage.
