"He (Rahul) sees himself as more of a Sunny Deol kind of a person. He is more of an action hero in that capacity," Pooja said here.
"There were a lot of rumours that Rahul is in 'Jism 2', but there was no chance that he would have been in 'Jism 2' because it is not in his temperament. He is not the kind of guy who would want to be in an erotic film. He is a different kind of a guy," she added.
Rahul, a fitness trainer, last appeared in TV reality show "Bigg Boss 4".
While his family is known to give a good break to newcomers, Pooja says Rahul wants to take his own time to get into showbiz.
"Rahul was offered 'Kalyug', but earlier the film was titled 'Blue Film' and he didn't like the title. He was very uncomfortable with it," said the elder sister, who has helmed movies like "Paap" and "Jism 2".
She says Rahul, 30, is closer to their father, veteran filmmaker Mahesh Bhatt.
"Rahul will never do what somebody else will ask him to do. Later, I wanted to make a film with him which was called 'Mushkil', which my assistant was supposed to direct. He said, 'no I am not ready'. (So,) He is taking his own time which is fair enough," added Pooja, who is assured Rahul will do a film only on his own terms.
"He will do a film when it is on his terms and he is in a position to do it. He doesn't depend on his father or me. He is extremely well in his business, and he is self-reliant boy. So let him enjoy the privilege," Pooja said.
