'If we ride together, we ride for justice': The story behind the mask revealed in first full-length trailer for The Lone Ranger

There has been little revealed about the plotline of the forthcoming Lone Ranger movie.
However, after the release of the new full-length trailer, it appears film-makers will be going back to the beginning of The Lone Ranger's story.
In a new trailer released on Tuesday, the reason the Ranger decided to wear the mask and how his friendship with his sidekick Tonto came to be is revealed.

It's about time: Johnny Depp as Tonto and Armie Hammer as The Lone Ranger in the forthcoming full-length trailer

The man behind the mask: A dazed and confused John Reid wakes up after his brush with death

The promo starts with Texas ranger John Reid, played by Armie Hammer, waking up marooned high on a wooden tower, covered in mud and confused.
After climbing down, he meets Native American Tonto - Johnny Depp - for the first time talking to a horse Silver.
A baffled John asks: 'Why are you talking to that horse? Why am I covered in dirt?'

What's going on? John comes to, unaware he's several feet up in the air

Where am I? John wakes up to find himself marooned on a tower

Tonto replies: 'I buried you.'
Still confused, John adds: 'Why am I alive?'
In flashbacks, Tonto tells him how: 'Eight men rode into canyon. I dug seven graves. Horse says you are spirit walker. Man who has been to the other side and returned. Man who cannot be killed in battle.'

First encounter: John happens upon Tonto talking to the horse Silver

Wary: John asks Tonto why he's talking to the horse... and why he's alive

The pair decide to team up battle greed and corruption, with John - who is thought to be dead - hiding his identity with a mask.
As they decide to work together, he tells Tonto: 'If we ride together, we ride for justice.'
A flashback shows Tonto standing in the middle of burned out tipis, saying: 'Justice is what I seek.'

All knowing: Tonto claims the horse claims John is a spirit walker

Lucky one: John is the only one out of the eight rangers to survive

He urges John to take on his crime-fighting alter ego The Lone Ranger: 'People think you are dead. Better to stay that way...
'There come a time when good men must wear mask.'
With The Lone Ranger's beginning then explained, the trailer continues with a flash of action scenes, involving galloping on horses, a runaway train and Helena Bonham Carter pulling out a gun.

Speaking about the film, director Gore Verbinski said: 'I have always been intrigued by characters who exist at times of monumental change. They are somehow cast against the events that engulf them and magnified.
'The Lone Ranger is a story of two outcasts bonded by adversity at a time when the lines between right and wrong have become blurred. With no well defined beacons to aid them, and no tribe to return to, they are a glorious pair of misfits: A band apart.'
The Lone Ranger first appeared in a radio show in 1933, before being transferred to the black and white TV show in 1949, starring Clayton Moore as the Lone Ranger and Jay Silverheels as Tonto.

There were two previous attempts at Lone Ranger films in 1981 and a TV movie in 2003, but they weren't received as well as expected by fans.
The film has been a long time coming; Columbia Pictures and Classic Media announced their intention to make a Lone Ranger film in 2002.
After years stuck in development, Disney announced in 2008 they had cast Depp to play Tonto, with filming finally started earlier this year.
The Lone Ranger is due for release in the UK on 9th August 2013.

Good V Evil: As with all good westerns, the film involves lots of horseback chasing scenes
