Marion Ravenwood is anything but a minor character in the hearts of fans.
However, in the recent film Indiana Jones and the Dial of Destiny, it seems that Karen Allen's role has been reasonably diminished - and Allen has spoken up about her unhappy feelings about the decision.
Since this movie is actually the last instalment of the movie, fans were hoping that it would go out with a bang. Often this means revisiting all of a flick's favourite characters, if possible. With Shia LaBeouf not returning, Allen's character was the remaining member of their little family to make a comeback in the film.
