The actor last week distanced himself from any potential film follow-up, saying that there are no "concrete plans" to bring the comedy back to the big screen.
Speaking to ShortList, the Friday Night Dinner star admitted that another Inbetweeners film is dependent on creators Iain Morris and Damon Beesley.
"I can tell you that I don't know anything [about a sequel]," he said. "None of us four [actors] have ruled ourselves out, but it's about whether Iain and Damon think they can make it as good as the first one.
"I know they're currently trying to think of ideas, and Channel 4 and everyone else are obviously very keen for it to happen."
"We have a brotherly relationship because we grew up doing that show and shared that experience of becoming famous together.
"It's a very deep bond. When we meet up, we immediately fall back into a relationship which is sort of based on our Inbetweeners characters. We're far more mature with our other friends than we are when it's just the four of us together."
Reports recently surfaced claiming that Morris and Beesley were working on a second big screen instalment for The Inbetweeners. The 2011 comedy broke records at the UK box office, netting £45 million during its summer cinema run.
