'PK' posterFacebook/PK The Film

Aamir Khan's 'PK' might be this year's most-awaited film, but unfortunately nothing has been going in the makers' favour.

After being in the news for chopping off Anushka Sharma's role in the Raju Hirani directorial, the superstar's effort to offer another unique film has hit a roadblock.

It turns out that the upcoming comedy-drama has a striking similarity with Hollywood star Kevin Spacey's "K-Pax" (2001). Directed by Iain Softley, the sci-fi mystery film revolves around Prot (Spacey), who is committed to a mental health facility and calls himself an ET from planet K-PAX. If not the entire plot, the skeleton of Khan's character does seem to be identical.

"It seems like Aamir is on some kind of a mission in this film that is similar to the one Spacey's character was on in the Hollywood movie," Hindustan Times quoted a source as saying.

However, this is not the first time that the film has been met by claims of plagiarism. A couple of days after the first poster of "PK" was released, in which Khan poses nude with just a transistor for covering his privates, there were reports that the first-look was an unabashed rip-off of Portuguese musician Quim Barreiros' album cover.

To add to it, there was a strong buzz that the film's plot might be along the lines of the 1995 Australian film "Alien Visitor". However, according to the makers of "PK", the protagonist isn't playing an alien.

"No one is aware of Aamir Khan's character in the film. In fact, at a press conference recently, Aamir and Raju even laughed off the rumours that the actor was playing a drunkard, alien or madman," an official spokesperson confirmed.

Set to release on 19 December, "PK" features Anushka Sharma, Sushant Singh Rajput, Sanjay Dutt and Boman Irani in key roles.
