Six people were injured in an apparent propane explosion on a movie set just outside Vancouver Tuesday afternoon.

The explosion occurred on the set of "In the Name of the King 2," which stars Dolph Lundgren. The movie is filming in Golden Ears Provincial Park in Maple Ridge, B.C. The town is about 40 minutes east of Vancouver.

All victims have been transported to hospital to be treated for non-life-threatening injuries. Maple Ridge Fire Department Chief Dane Spence told The Canadian Press that six people sustained minor burns and one victim also had a broken leg.

"What made it a little difficult to diagnose these people is that many of them had black face paint on and medieval-type clothing from the movie set," Spence said.

An air ambulance had been called but was cancelled when the victims were all found to be conscious.

Spence said early reports suggest the blast occurred as propane was being transferred from a tanker to portable containers. A hose became dislodged from the propane tank during the transfer, Spence said, and a nearby heater sparked a flash fire.

The RCMP and WorkSafeBC are investigating the incident.

The film is a sequel to the 2008 film "In the Name of the King: A Dungeon Siege Tale," a movie inspired by the Dungeon Siege video games. The film, which bombed at the box office, won the worst-director award at the Razzies, which salutes the worst films of Hollywood.
