Film locked in for 2015 release.

Word is coming in from multiple outlets that Sony Pictures is planning a film adaptation of Dan Brown’s latest Robert Langdon-centric novel ‘Inferno’ with release set for 2015.

Tom Hanks, who portrayed the Harvard symbologist in the two previous adaptations, 2006s ‘The Da Vinci Code’ and 2009s ‘Angels & Demons,’ will reprise the role once again, with Ron Howard back in the director’s chair.

‘Angels & Demons’ screenwriter David Koepp is on board to provide the screenplay.

Released in May, ‘Inferno’ sees Professor Langdon and his new partner, Dr. Sienna Brooks, battling a chilling new adversary who threatens to unleash a plague, following clues from ‘The Inferno,’ the first part of Dante Alighieri’s 14th-century epic poem ‘Divine Comedy.’

Sony was initially developing an adaptation of Brown’s third book in the series, ‘The Lost Symbol,’ and was believed to be in talks with Mark Romanek to direct, but those plans appear to be on the backburner for now.
