James Franco and his grandmother have recorded a cheeky video message.

The 32-year-old actor - who is to host the 2011 Oscars alongside Anne Hathaway - decided to record a Christmas greeting with his elderly relation, and address fans who are too scared to watch his new thriller '127 Hours'.

Following the true story of mountain climber Aron Rolston - who was forced to cut off his arm after he was trapped by a boulder for five days in a canyon in Utah - the gruesome scene in which he severs off his limb has caused many cinemagoers to pass out while watching it.

Speaking to his grandmother in the video message, James said: "There are some people that hear about this movie and they're a little scared to see it. I was wondering if you could tell everybody what you thought of those people."

She then turns to the camera and shouts very loudly: "I think they're a bunch of p*****s!"

After collapsing into a fit of giggles at his grandmother's comments, James then wished his fans a merry Christmas.
