Abhishek Bachchan teams up with Ekta Kapoor

Abhishek Bachchan is gearing up for the biggest challenge of his career. He will be playing the solo hero in an action film to be produced by Ekta Kapoor. This would be the kind of hi-tech action thriller that belongs to the Bourne Identity-Dhoom genre.

Says a source close to Abhishek, "Ekta sees illimitable untapped potential in Abhishek especially as an action hero. In fact not since Vidya Balan has she got so much faith in any actor to deliver the goods."

Apparently, the czar of Balaji films has requested Abhishek to keep the second-half of 2012 free for the action film.

Says the source, "Abhishek has spent the first few months of 2012 completely immersed in Bol Bachchan. He now needs time to prepare Ekta's film. There's also Dhoom 3 which requires intense preparation. But its Ekta's film for which Abhishek is getting into sinewy shape."
