The actor's Kingdom Of The Crystal Skull co-star Shia LaBeouf - who played the titular character's son - recently admitted that director Steven Spielberg had "cracked the story" for the proposed fifth instalment.
Ford explained that he is prepared to revisit his adventurer archaeologist character if the script "is good", according to Extra.
"The story for the new Indiana Jones is in the process of taking form," he told Le Figaro.
"Steven Spielberg, George Lucas and myself are agreed on what the fifth adventure will concern, and George is actively at work. If the script is good, I'll be very happy to put the costume on again."
The fourth Indiana Jones film topped a list of the most mistake-filled movies of 2008.
