The 13 most famous movie quotes of all time still used today - how many do you remember?

Robert De Niro is acting royalty for a reason and certainly showed off his chops in Martin Scorsese's 1976 classic Taxi Driver. 

In fact, the actor improvised his iconic line "You talkin' to me?" while his character Travis Bickle acts out an imagined confrontation in the mirror.  

James Bond spoof hero Austin Powers has made his way into the public lexicon to an even greater extent than his 007 cousin. 

From coyly quoting "Oh, behave!" to the pinky propped saying "One million dollars!", the franchise has plenty of catchphrases to choose from. But it's "Groovy, baby!" that we keep coming back to at every occasion.

Jerry Maguire may have had us at hello, but it's "Show me the money!" we're still quoting to this day. As Rod Tidwell says, you've got to yell it for the full effect.

From gifs to custom mugs, it's an almost inescapable phrase that any movie buff likes to slip into conversation wherever possible.

Best used for comedic effect when you're disappearing for about 30 seconds, "I'll be back" has everyone trying to imitate Arnold Schwarzenegger's trademark line and recognisable accent to the best of their (limited) abilities.

The bodybuilder, actor and former Governor of California has certainly made his mark on cinema but it's this calmly uttered phrase before he crashes a police car through the station that's stayed in our minds.

It's not personal, Sonny. It's strictly (show) business. The Godfather brought Marlon Brando's mob boss to the big screen in the almost three-hour crime epic. 

Whether your offer is as persuasive as Brando's doesn't matter too much, the quote's power comes entirely in the delivery and the ridiculous nature of your proposed swap. 

While the fact of whether it's actually a corner Patrick Swayze finds Jennifer Grey in, or just an unfortunately placed pillar, has been thoroughly debated, Dirty Dancing's famous phrase itself has been firmly lodged in conversations since the '80s. 

It likely helps that the saying was first uttered on-screen by heartthrob Johnny Castle and led to one of cinema's most iconic dance sequences.

Tom Cruise is happily at home in our list of iconic movie quotes already, but this time it's scene partner Jack Nicholson who delivered the memorable phrase. 

Colonel Jessup screams to Cruise's Lieutenant Kaffee in defence of his harsh methods, arguing that civilian morals are facilitated by the actions of the military.

This villainous phrase has been stripped of some of its power as many movie fans decide to utter it to comedic effect on a particularly sunny day, or when there's a particularly strange whiff in the air.

In Apocalypse Now, the saying has a far more sinister reality: Robert Duvall delivers it after a huge napalm strike on a Vietnamese beach so his soldiers could surf. 

Arriving in the middle of a tense situation or simply want to make an impact down a suitably splendid staircase? There's no better inspiration than Gloria Swanson's Norma Desmond.

The more eccentric the outfit and the bigger the crowd the better. Make sure your (imagined) last steps of freedom are drop-dead gorgeous like they do in Sunset Boulevard. 

Not many movie quotes become so iconic that they are quoted back on the screen. The Graduate's Mrs Robinson has inspired series like The Simpsons, rom-com Rumor Has It... and American Pie. 

In fact, Mrs Robinson herself has become the definitive example of on-screen flirtations between young men and older women.

It's the phrases that best sum up our day-to-day that stay with us best. Ever bitten into a truffle hoping for gooey caramel and getting sickly strawberry cream? Then you'll likely relate to Forrest Gump's oft-quoted saying.

Tom Hanks brings the varied and touching story of Forrest and his lifelong love for girl-next-door Jenny to life and is regularly quoted whenever something doesn't go quite to plan.

While Al Pacino in Scarface had terrifying intentions with his so-called 'friend', nowadays, the phrase is just as likely to be said humorously holding your brand new kitten.

Uttered during the film's climax, the delivery pre-empts a slew of violence by the villainous Tony Montana at the heart of 1983's Scarface. 

Casablanca is a classic among classics. Starring Humphrey Bogart, Ingrid Bergman and Paul Henreid, the film defined star-crossed love for the cinema age.

In its closing scenes, right after a tear-jerking end, Humphrey's Rick walks off with Claude Rains' Captain Louis Renault, an unlikely friendship that takes the pair to join the Free French forces.
