Tom Ford Snowdon - Ryan Reynolds - The Hitman's Bodyguard
The brand can be recognized by the T-line on the temples, a typical Tom Ford design element.
The Tom Ford Snowdon glasses seen in the film are either black or dark Havana. It is the same model worn by James Bond in SPECTRE (2015), but Reynolds himself wore the same model sunglasses in the 2015 film Selfless, so even before Bond wore them.
