30 Seconds To Mars hitmaker Jared Leto has revealed that he employed some of his own grandmother's mannerisms when he starred in the new movie 'Dallas Buyers Club', which has already received great acclaim as well as several awards. 

In the film, Leto portrays a transgender and HIV positive character named Rayon and he confessed to Kiss FM's Breakfast Takeaway that he took on board the way his grandmother would use a term of endearment at the end of each sentence she said:

"I waxed my whole body and my eyebrows I lost a lot of weight, I changed my voice - the dialect and register - it was a pretty intense journey. [Saying 'Darlin'' at the end of sentences], my grandmother used to do that, she was from the South and there was certainly a bit of grandma in there."

The superstar also opened up about the weight he lost for the role and explained that starving himself was incredibly tough: "When you starve yourself for that long, you cant even eat a tablespoon because you get full. You think you're going to have this huge meal and then you're stuffed after a couple of bites and can't enjoy it, everything is weird, it takes a while to get back to normal."

"And you start gorging when you do stretch your stomach a bit. It's hard to stop eating."

Leto is up for an Oscar at this year's ceremony for Best Supporting Actor in 'Dallas Buyers Club'. The 2014 Oscars will take place on March 2.
