‘Highlander’ star Christopher Lambert, 69, collapses at Pittsburgh Comic-Con

“Highlander” actor Christopher Lambert suffered a medical emergency while attending the Steel City Comic-Con in Pittsburgh.

At the annual convention on Saturday, the French actor, 69, was signing autographs for fans when he “suddenly collapsed,” a witness told TMZ.

Lambert was then placed in an ambulance and transported to a local hospital.

The Steel City Con also released a statement about the incident, saying Lambert “had to leave the event due to a personal issue.”

The comic book and pop culture convention also announced that Lambert’s photo op was canceled.

A rep for the “Mortal Kombat” star told TMZ that he is “perfectly ok” and resting in his hotel room.

The spokesperson claimed that Lambert did not get enough sleep the night before the convention and hadn’t eaten much during the day, which prompted his blood sugar to drop.

It’s unclear whether Lambert will attend the convention on Sunday; however, the outlet was told that he will be well enough to make his scheduled appearance at FAN EXPO in Chicago next week.

Page Six has reached out to Lambert’s rep for comment but did not immediately hear back.

Last year, Lambert suffered a health scare when he injured his back after falling down a flight of stairs at his hotel.

Due to the severity of the injury, the “Highlander II: The Quickening” star had to drop out of an appearance at the Swedish festival SciFiWorld last March.

“As an actor, filming and promoting his films are an absolute priority and has always been, and while he has the highest respect for people organizing events and fans who attend,” his reps said at the time.

“Unfortunately this time he will not be able to attend the comic con,” they added.
