The quiz show branded "television's toughest" could be on the verge of a revival after a 13-year break.
ITV bosses are poised to order a new series of The Krypton Factor, according to Broadcast.
An insider described the original show as "terrific", adding that "everything eventually comes back into fashion".
An ITV spokeswoman said the broadcaster is "always looking for the best possible programmes for all of its channels".
The Krypton Factor was axed in 1995 after an 18-year run on Monday nights. The programme saw four contestants taking part in a number of challenges to test their mental and physical abilities, including a gruelling assault course.
It was among the top ten shows chosen for a TV return in a public poll taken at the start of the year.
