Harrison Ford, Steven Spielberg and George Lucas have all arrived on the Big Island of Hawaii this week to begin filming scenes for next summer's Indiana Jones 4. According to The Hollywood Reporter, the film will be shooting there for the next three weeks.

The production team will be filming scenes along the Hamakua Coast, just north of Hilo. Other scenes were shot earlier this month in New Haven, Connecticut.

Paramount is keeping quite mum on what is exactly being shot in Hawaii. And, despite rumors, the film doesn't even have a title yet. Some thought it was going to be called Indiana Jones and the City of the Gods but that simply is not true at this point.

Indiana Jones 4 opens May 22nd, 2008.

Indiana Jones and the Kingdom of the Crystal Skull was released May 22nd, 2008 and stars Harrison Ford, Cate Blanchett, Karen Allen, Shia LaBeouf, Ray Winstone, John Hurt, Jim Broadbent, Igor Jijikine. The film is directed by Steven Spielberg.
