LOS ANGELES (AFP) - Martin Scorsese's The Wolf Of Wall Street and Disney's animated fantasy hit Frozen were the two most pirated films of 2014, according to a firm tracking illegal downloads.

Numerous United States media, including Variety and The Hollywood Reporter, on Monday published a list of this year's 20 most illegally downloaded movies, compiled by piracy tracker Excipio.

The firm tallied "torrent" downloads, where computer users illegally share movies and other media over the Internet, for the period from Jan 1 to Dec 23, according to Variety.

Excipio said The Wolf Of Wall Street was illegally downloaded more than 30 million times, while Frozen was pirated more than 29.9 million times.

In third place was RoboCop, with a little less than 29.9 million illegal downloads, though this included both 2014's re-booted version and the 1987 original.

Space drama Gravity, directed by Mexico's Alfonso Cuaron, was downloaded just under 29.4 million times.

Popular among the pirated films were several superhero adventures, including Thor: The Dark World, Captain America: The Winter Soldier and X-Men: Days Of Future Past.

Each of these racked up more than 20 million illegal downloads.

This year's best-film Oscar winner 12 Years A Slave was illegally downloaded 23.7 million times, while American Hustle and Captain Phillips were pirated 23.1 million and 19.8 million times respectively.
