The American actor played Detective John Blake in the third film of The Dark Knight trilogy, with many fans hoping he was set to fill the caped crusader’s shoes in a forthcoming instalment, taking over from Christian Bale.

Although the 2012 movie hinted that Blake would become Batman, a standalone film has never materialised, and Joseph admits he’s glad that’s the case.

“I know we're all used to the sort of Marvel movies, which are just kind of endless series,” he told Cinema Blend. “They don't really have a beginning, middle, and end. But I think Nolan very much thought of that movie as a conclusion, and there's a theme that runs through all three of those movies that begins in the first movie, runs through the second movie and it concludes in that moment where he says that Batman is more than a man, Batman is a symbol. And so to have another man other than Bruce Wayne kind of becoming Batman at the end of that trilogy, I think that's the perfect ending to that story.”

While helming the role of Batman would be Joseph’s biggest role to date, the actor’s schedule is always jam packed. The 35-year-old has become known for his varied film roles, and in recent years has played everyone from real life high-wire walker Philippe Petit in The Walk, to loveable Ethan in Christmas comedy The Night Before.

Next up audiences will see Joseph as Edward Snowden, the former CIA employee who leaked classified information from the National Security Agency (NSA) in 2013. Snowden hits cinemas from September (16).
