These films are featured in Concrete Circus. The stunts in them were carried out by experts in a controlled environment and there were safeguards in place.
For example, for the fire stunts in Storm Origins, Blue wears a cooling protective layer beneath his jeans.
The film-makers had permission to film in all the locations you see. Thorough risk assessments were carried out and all stunts were performed under the supervision and instruction of a stunt co-ordinator.
Don't try these stunts yourself.
We suggest they're viewed by over 18s only.
Concrete Circus was produced and directed by Mike Christie:
