Will Smith and Michael Bay were seen walking along Santa Monica’s boardwalk on February 7, fueling speculation of a Bad Boys reunion.
The duo, who collaborated on the 1995 action comedy, appeared relaxed and upbeat.
Witness Niko Williams said they might have been discussing a project or scouting locations.
Smith, 56, engaged warmly with fans.
Reports last year suggested Bay was in talks to direct Smith in Netflix’s Fast and Loose, a thriller about a man uncovering his dual life as a crime boss and CIA agent after waking up in Tijuana with no memory.
