Harrison Ford's final outing as Indiana Jones will be "emotional and exciting" as the franchise heads back to its roots after a badly received fourth installment.
Ford is well-known for his portrayal of the archaeologist and adventurer, and has agreed to reprise the role one last time.
Indiana Jones 5 will begin shooting next year, and much of the plot line will be centred around the Bermuda Triangle, an area over the North Atlantic Ocean where a number of aircraft are said to have disappeared.
"George (Lucas) and Steven (Spielberg) have been working on a script and it's almost there," a source explained.
"Harrison is on stand-by for filming next year. This looks like being an emotional and exciting conclusion to the franchise, with Indy facing his biggest challenge yet."
