From self-referential nods to the director's previous works to gentle jibes aimed at the cast, cinema is full of private jokes and esoteric gags, sneaked in by the filmmaker (well, if you've got the power...). The question is, did you spot any of them?

And it isn't just the deliberate tricks that make it past the final edit, even the slickest films with the biggest budgets are riddled with bloopers (did somebody say 'Skyfall'?) that somehow make it onto the silver screen. Did you catch any of these the first time round?

  • Star Wars Episode IV: A New Hope

    When a <a href="" target="_blank">Stormtrooper bumped his head on a doorway</a>, in an unlikely 'You’ve Been Framed' moment on the Deathstar, George Lucas did what any self-respecting director would have done – he left the gaffe in. And in doing so, catapulted the clumsy Stormtrooper to world-famous cult status. He even paid homage to the blooper in 'Episode II: Attack Of The Clones' with Jango Fett also bumping his head on a doorway.

  • Indiana Jones And The Temple Of Doom

    In ‘Indiana Jones and The Temple Of Doom’, you may have spotted a glimpse of the theatre called Obi Wan – a nod to 'Star Wars' creator George Lucas, who was writer and executive producer on the Indiana Jones series. But that wasn’t his only self-referential joke. In the first film, ‘Raiders Of The Lost Ark’, the seaplane on which Jones escapes in the opening scene has a registration number, OB 3PO.

  • Mr And Mrs Smith

    Benjamin ‘The Tank’ Danz (Adam Brody) is aptly dressed in a ‘Fight Club’ T-shirt for his capture, and subsequent torture, by his assassins, Mr and Mrs Smith (Brad Pitt and Angelina Jolie). Director, Doug Liman, claims the cheeky wardrobe decision was less an homage to the film’s star, Brad Pitt, and more to remind the audience not to take the film too seriously.

  • Charlie's Angels

    When ‘Charlie’s Angels’ private investigator, Dylan Sanders (Drew Barrymore), crash lands in a garden, in the buff (don’t ask), many viewers will have noticed the no-so-subtle nod to the actress’s debut film, ‘ET’. Two boys are sitting in their living room, so engrossed in a video game, they fail to notice the naked woman standing outside the patio door, but few viewers will fail to notice the ‘ET’ poster hanging above the TV. And that's not all, according to his DVD commentary, director McG used the same house set, in which ‘ET’ was filmed.

  • Home Alone 2: Lost In New York

    In the ‘Home Alone’ sequel, Kevin McCallister (McCauley Culkin) wanders into The Plaza Hotel in New York, where he tricks the staff into giving him a room on his father’s credit card. But who is the familiar figure he stops to ask directions to the lobby? With that golden barnet, it could only be the Plaza’s real-life owner, renowned business magnate and star of America’s ‘The Apprentice’, Donald Trump.

  • It's A Wonderful Life

    When Uncle Billy staggers out of George’s house, drunk, it sounds as though he has crashed into some rubbish bins on his way out. But the almighty clatter was in fact a clumsy stagehand that dropped some equipment during the take. True professionals, the actors carried on, with Thomas Mitchell ad-libbing the line, “I’m all right, I’m all right!”. The director not only left in the accidental sound-effect but gave the crew-member $10 for “improving the sound”.

  • Men In Black 3

    According to movie bloopers site, <a href="" target="_blank"></a>, ‘Men In Black 3’ beats ‘Skyfall’ as the most mistake-ridden film of 2012. As continuity mistakes go, this one has got to be one of the most blatant. When Agent J (Will Smith) is frisked by the police, by the roadside, <a href="" target="_blank">he is glasses-free one minute and adorned with black shades the next</a>. It would seem Will Smith isn’t the only one who should have been wearing glasses throughout the scene, if this one wasn’t picked up in the editing suite.

  • Pulp Fiction

    With its time-hopping, topsy-turvy narrative, you could be excused for not keeping up with the order of events in ‘Pulp Fiction’. Shame Tarantino and his crew couldn’t keep up with the order either. Numerous continuity errors have been spotted in the cult hit film but perhaps the most famous is in the ‘miracle’ scene where Jules and Vincent are about to be shot. But <a href="" target="_blank">aren’t those bullet holes right behind them?</a>

  • Spiderman 3

    Another gaffe-filled movie is Spiderman 3, released in 2007. Here, the <a href="" target="_blank">same couple walks past Toby McGuire, in the same direction</a>, in two different shots. Oops!

  • Pirates Of The Caribbean: Curse Of The Black Pearl

    Aaaaaarrh! Not another mistake. This film is <a href="" target="_blank">jam-packed with bloopers</a> - perhaps not that surprising in a production of this scale. Our favourite has to be the crew member who escaped notice in his cowboy hat and sunglasses. A cowboy film, maybe but, come on...
