Set before the events of the original trilogy - which saw Viggo Mortensen take on the role of the Ranger of the North - the spin-off programme is thought to have $1 billion available.

Although details and casting have not been confirmed, fan site, has suggested the time frame means the 51-year-old actor is unlikely to reprise his part.

The website spoke to "multiple sources" regarding the upcoming, highly anticipated project, and posted a series of tweets teasing what fans could expect from the latest adaptation of J.R.R. Tolkien's fantasy epic.

They wrote: "From the first press release, we know this so-called #LOTR series will NOT be a retelling of the events of the War of the Ring. #BeenThereDoneThat.

"Instead it will be Appendices based and cover a lot of time and history. This is the greatest advantage the show runners have: that so much of Tolkien's storytelling, even just in 'Appendix A,' covers a tremendous swath of time.

"On what Amazon may choose to do with the King of Gondor, the fans continued: 'Starting with a young Aragorn narrative allows connections to his Numenorean bloodline (and to the founding of #Gondor).' "

The 'Lord of the Rings' trilogy - originally released from 2001 to 2003 - became one of the highest-grossing movie series in history, bringing in around $2.8 billion across the globe.
