Sources revealed the tale, which is being shot across Scotland, will not include the 14th-century king’s most famous victory at Bannockburn.

But backers Netflix are said to be already planning two sequels that will complete his life story.

A film insider told The Scottish Sun on Sunday: “This is just the beginning.

“The main battle in Outlaw King is the 1307 Battle of Loudoun Hill, which was Robert the Bruce’s first major military victory.

“The Battle of Bannockburn seven years later will have to wait until the sequels.”

Star Trek and Wonder Woman actor Chris Pine stars as Bruce, with Scots actor James Cosmo as his father.

Stephen Dillane, who played Stannis Baratheon in hit TV series Game of Thrones, is Edward I of England.

Extra Jamie McGeechan said: “The fight scenes are epic. A couple of special effects guys told me if people were impressed by the blood and gore of Braveheart, they haven’t seen nothing yet.

“The gory scenes are going to blow folk away.”

Scots director David Mackenzie is gunning for Oscar glory after four Academy Award nominations earlier this year for Hell or High Water.

And he enlisted crew and stuntmen from Game of Thrones to ensure harrowing battle sequences.

One will include a horse being sliced in half by English marauders.

A robotic animal was used that is so lifelike, shocked extras feared a real one had been killed.

A crew insider revealed: “The mechanical horse gets sliced open while on its hind legs.

“It looks so real from close up it fooled some of the cast and crew.”

Cosmo said: “It’s going to look extraordinary.”
