This was noted by historian Fern Riddell, who tweeted: “Look I love Jodie Comer, I think she’s amazing, but this is just another example of Hollywood’s obsession with younger women.
However, some fans supported the casting, with one tweeting: “Jodie Comer could make Josephine a really enigmatic and interesting character.
Jodie Comer is 18 years younger than Joaquin Phoenix.”
