Ron Howard and Brian Grazer have been seeking funding for their Dark Tower project at the Cannes Film Festival.

The producers have streamlined their ambitious plans in order to find an investor for their Stephen King adaptation, Digital Spy reports citing Deadline.

Media Rights Capital is to fund one movie based on the seven-volume fantasy/Western saga, with more to come if the first succeeds.

Grazer also said that they were in talks with a Silicon Valley investor who is willing to fund the multiple-film project as previously planned.

Russell Crowe is in line to play last Gunslinger Roland Deschain in the adaptation.

The Dark Tower has already passed through the hands of Universal Pictures and Warner Bros.

King recently returned to the franchise with the supplementary novel The Wind Through the Keyhole.
