Iron Man 3 and Man of Steel shouldn't have been in 3D says James Cameron

James Cameron has said that neither 'Iron Man 3' or 'Man of Steel' should have been made in 3D.

The 'Avatar' director, who was among those pioneering the resurgence in 3D technology with his 2009 film, made the comments at the TagDF technology conference in Mexico City.

“I do not think Hollywood is using the 3D properly,” he said. “The reason I say that Hollywood is not doing well is because it is automatic.

“For example, 'The Man of Steel,' 'Iron Man' and all those movies should not necessarily be in 3D. If you spend $150 million on visual effects, the film is already going to be spectacular, perfect.”

“One thing is shooting in 3D and another to convert to 3D. After 'Avatar' changed everything, good and bad movies, everything has to be in 3D since 'Avatar.'

“The problem I see now is that instead of it being a filmmaker issue is a matter of the studios to make money and are pushing 3D to directors who are not comfortable or do not like 3D.”

The comments echo recent remarks from director Louis Leterrier, who has admitted that his 3D conversion of 'Clash of the Titans' was 'horrible'.

Cameron also added that he is pursuing his plans to make the movie 'Battle Angel' once he's wrapped up his 'Avatar' trilogy, likely to be around 2017.

An adaptation of a Manga series, it focusses on Alita, a amnesiac cyborg who is rebuilt by a cybernetics doctor and becomes a bounty hunter while trying to discover her past.
