Hrithik Roshan has been stepping up his game for Ashutosh Gowariker's "Mohenjo Daro". There have been reports of him filming action sequences which have never been seen before.

According to an India TV news report, the superstar will fight a 20-foot-long crocodile for one of the scenes in the film. Unlike his tussle with tigers in the film, the combat with the gator in question will be shot with the help of special effects.

Also, the actor will reportedly be seen taking on a tiger in the period drama.

"The script of Mohenjo Daro is superb. Hrithik is my friend and he has shared with me the details of the body shots and other sequences while working out. There are combat scenes between him and tigers in the film. So I'm training him to build the right body for these kinds of sequences," Satyajit Chaurasia, Hrithik's trainer, told IANS a few months ago.

Another interesting trivia which has trickled in is the passionate love-making scene the lead actor will be shooting soon. Said to be over two-minute long, the scene is to be shot in a cave with newcomer Pooja Hegde.

If this isn't thrilling enough for the star's fans, then there's another piece of news which has been doing the rounds for a few months now and it's nothing like he has done before. Apparently, Hrithik has dropped his clothes for the introductory scene, like how Aamir Khan did in "PK".

"Hrithik's opening shot in Mohenjo Daro will have everybody talking. He has gone all out and will be seen in a look similar to that of Aamir Khan's PK," Bollywood Life quoted a source as saying.
