If latest reports are to be believed, two of the most-awaited films of 2014 are expected to clash at the box office in December.

Buzz is that Rajinikanth's Tamil film "Lingaa" will be releasing for the superstar's birthday on 12 December. The film, directed by KS Ravi Kumar, will have Rajinikanth appearing in dual role. Sonakshi Sinha and Anushka Shetty play the female lead roles opposite the superstar. The film's shooting is progressing well and is all set to be wrapped up soon.

Earlier, there were reports claiming that "Lingaa" will be releasing for Diwali in October, but now the buzz is that the film will make it to theatres in December as a special birthday treat for superstar fans. "Lingaa" producer Rockline Venkatesh is keen that the Tamil, Telugu and Hindi versions of the film should be released simultaneously on the same day, reported Sify.

If the Rajinikanth starrer releases on 12 December, it will be locking horns with Aamir Khan's most-anticipated Hindi film, "PK." The film, directed by Rajkumar Hirani, is all set to hit the screens on 19 December. The first-look poster of "PK", showing Aamir nude with a radio covering his private parts, has created a huge buzz surrounding the film.

This is the second time that the actor has teamed up with director Rajkumar Hirani post the stupendous success of "3 Idiots." Expectations are huge for "PK" and film is all set to have a grand release. The film's producers Vinod Chopra Films, Rajkumar Hirani Films and UTV Motion Pictures are reportedly targeting to release the film in more than 3,500 screens worldwide.

On the other hand, "Lingaa" makers are also planning to release the film in huge number of screens. However, the film will have an open run for only week, after which it will be facing stiff competition from Aamir Khan's "PK."

As far as box office is concerned, there is no doubt that Rajinikanth's "Lingaa" will dominate South India markets. But, the film is likely to face screen crunch in the North and key overseas markets like the US and the UK.

Rajinikanth films have done huge business in overseas markets. They play a significant role in getting a big opening for the actor's films. Similarly, Aamir Khan's films have also fared well overseas.

There will be competition from both the films to grab enough number of screens. It will be interesting to see how these films perform when they clash at the box office.
