Harrison Ford spoke with BBC ONE in London about the status of the next Indiana Jones film.
TheRaider.net reports Ford didn't give anything away, but mentioned the movie will happen:
As mentioned yesterday, BBC ONE just aired their first episode of a new programme called Hollywood Greats tonight. This first episode centered around Harrison Ford's career and included an extended interview with Ford, by British film critic Jonathan Ross. At the end of the great interview Jonathan asked Ford how much of a chance there was of another Indiana Jones film.
Harrison Ford stalled his answer for a few seconds and then responded that it was "99 and three quarter percent." likely to happen.
Then further asked if Sean Connery would return as Indy's father in Indy IV, Ford declined to make a comment on that. Jonathan Ross responded with "So he's going to be in it, then." and Ford just kind of laughed and didn't say anything.
Indiana Jones 4 will continue the saga 10-12 years after Indiana Jones & The Last Crusade. As reported recently, Frank Marshall said they've looked at Australia as a possible shooting location starting early next year.
