French–American actor Christopher Lambert, 69, was treated by medics and transported to the hospital after collapsing during an autograph session at Steel City Comic-Con in Pittsburgh on Saturday (Aug 8). The Highlander star fell ill while meeting fans, prompting staff to call emergency responders and escort him from the venue, a witness informed TMZ. Convention organisers later confirmed Lambert had left due to a “personal issue”, and his scheduled photo op was cancelled. Witnesses said he appeared shaky before being placed in an ambulance and taken to a nearby hospital for evaluation. Lambert, known for roles in Highlander, Highlander II: The Quickening, Mortal Kombat and Fortress, regularly meets fans across around the world.
