Karen Allen wrote to Indiana Jones and the Dial of Destiny director and producer Kathleen Kennedy to tell them her character Marion Ravenwood should appear in the sequel.
The 73-year-old actress played Indy's love interest Marion Ravenwood in the original 1981 film Raiders of the Lost Ark and the 2008 sequel Indiana Jones and the Kingdom of the Crystal Skull and was set for a significant role in Disney's fifth film, released in 2023, when Steven Spielberg - who helmed the previous four films - was set to direct from a script by David Koepp.
