Actor Medical Emergency Sparks Concern at Convention
Despite the frightening incident, Lambert appears to be doing well following the health scare.
A spokesperson for the actor told TMZ that Lambert is "perfectly ok" and was resting in his hotel room after leaving the hospital.
The spokesperson explained that low blood sugar caused Lambert to collapse after he had little sleep and had not eaten much throughout the day.
It remains unclear whether Lambert will return to the Pittsburgh convention on Sunday.
However, the actor reportedly still plans to attend FAN EXPO Chicago next week.
The event will take place at the Donald E. Stephens Convention Center from August 14 through 16.
Lambert features on a star-studded guest list alongside Mel Gibson, Kurt Russell, Elijah Wood, Mr. T and William Shatner.
According to the event's website, Lambert is scheduled to appear across all three days of the convention.
Christopher Lambert Previously Suffered a Serious Fall
Beyond Highlander, Lambert has built an extensive acting career spanning more than four decades.
He played Raiden in 1995's Mortal Kombat, Methodius in Ghost Rider: Spirit of Vengeance in 2011, and Arne Seslum in Hail, Caesar! in 2016.
Lambert began his career with supporting roles in several French productions before achieving international recognition as Tarzan in 1984's Greystoke: The Legend of Tarzan, Lord of the Apes.
For his French-language work, the actor is credited as Christophe Lambert.
Saturday's incident comes after Lambert suffered another health setback last year.
In March 2025, reports revealed that the French-American actor tripped on stairs while entering a hotel and suffered a back injury that required physical therapy.
Lambert had been scheduled to attend SciFiWorld, a Comic-Con-style event in Sweden, but organizers canceled his appearance and described the fall as a "serious accident".
The actor subsequently underwent rehabilitation and recovered from the injury, allowing him to return to public appearances and conventions.
