Some believe Neeson's villainous character will be used in flashback scenes.

Liam Neeson will reprise his role of Ra's Al Ghul for the Dark Knight Rises, the next Batman film on the horizon.

Ra’s al Ghul was the man who trained and who ultimately turned against Bruce Wayne in 2005’s Batman Begins.

He was killed in that film and Female First UK speculates that "Neeson's villainous character will be used in flashback scenes, with actor Josh Spence already confirmed as a younger version of Ra's Al Ghul."

Christian Bale, Gary Oldman, Tom Hardy and Anne Hathaway also star in the much-anticipated superhero blockbuster.

More Movie Notes...

The aforementioned Liam Neeson and Ralph Fiennes revealed they think they had a "godly bromance" on new movie 'Wrath of the Titans,' while doing an interview to promote the movie.

Liam and Ralph play king of the gods Zeus and Hades, god of the underworld, respectively in the mythical blockbuster and the pair became good friends on set and had a hard time being serious in their scenes.

In a joint interview on British morning TV show 'Daybreak', Ralph said: "It's a romance, a Godly bromance. We go in very serious - like we're going to do this - and then we catch each other's eyes."

Liam added: "All these fake beards and long hair and costumes and stuff - you have to have a giggle."

The two actors also spent their time on set imaging who would win in a fight between two of their most famous characters - Ralph's Lord Voldemort from the 'Harry Potter' films and Jedi Knight Qui-Gon Jinn, who Liam played in 'Star Wars Episode I: The Phantom Menace'.

Ralph said: "He (Lord Voldemort) wouldn't stand a chance. The thing is, if Voldemort has wand power - you're finished. But once I get in a reach of these huge arms, then I'm done for."
