The 'Avatar' creator and his Lightstorm Entertainment partner Jon Landau are set to produce the remake of the 1966 sci-fi flick, 'Fantastic Voyage,' but if they are unable to acquire a well known actor then they may face losing the projects current director, Shawn Levy.

THR claim that Levy, the director of 'Night at the Museum,' 'Date Night' and Hugh Jackman's latest robot film 'Real Steel,' is set to leave the big budget movie in future weeks if a highly acclaimed actor does not star in the film.

Production has been on hold due to casting difficulties and this has resulted in Levy considering taking the lead in other less complicated projects. He already has many offers on hold including re-imaging 'Sleeping Beauty' or 'Frankenstein'.

Will Smith could be the last hope for Levy's involvement. Insiders have reported that Levy has arranged an appointment with Smith to discuss arrangements about the film in the hope that the 'Hancock' actor will sign on.

'The Fresh Prince of Bel-Air' star has been away from the big screen since 2008 in 'Seven Pounds,' although he is set to be busy with the release of 'Men in Black III' next year and music producer La Mar 'Mars' Edwards has suggested that Smith will be making a return to rap music. This implies that he may not have the time to commit to a new 3D blockbuster. However, he has had much experience in the sci-fi genre so it will be good news for both crew and fans alike if he does take on the offer.

'Fantastic Voyage' revolves around a group of scientists who shrink down to molecular size in order to enter the body of their friend and fellow colleague in the hope to save his life.
