Speaking after The Cube won the 'Entertainment Programme' prize at the Philips British Academy Television Awards, Schofield explained that he always knew the series would be a "monster show".
"You care about the people playing it," he said. "[The producers] have come up with the most fantastic, high jeopardy idea.
"It's the only show that I do where I lose sleep at night when I've played it. Either we've given someone a huge amount of money or we've lost someone a huge amount of money."
Schofield added that it is "fascinating to watch the human mind at play" and suggested that the effects on the show make it "breathtaking to watch".
He continued: "I've gone home thinking about what we've done in the studio, thinking about the positive aspects. And we've had people who've broken down and come apart in there. I've had to come in and help them because it's traumatic and highly emotional. So yes, I think probably of all the things I've done, this is the one that probably pumps me up the most."
Schofield also revealed that he is thrilled the show picked up a BAFTA, joking: "Beating The X Factor is delicious!"
