“Disney’s always been incredibly supportive of the LGBTQ community.

However news of Whitehall’s casting has caused fury among some fans and actors.
Omar Sharif Jr wrote: “Really @Disney #JungleCruise ? Your first significant gay role will be played by a straight white man perpetuating stereotypes? Fail! This ship should sink.”
Ethan Harvey said: “If only there were gay actors who could play ‘camp’ as well as Jack Whitehall.”
A fan tweeted: “Straight people playing gay camp characters is offensive. Period.
“Prove me wrong and tell me about all the gay camp actors that auditioned for this role but somehow @jackwhitehall was the best at doing it so he got the job fairly. I’ll wait.”
Jungle Cruise is based on the Disneyland theme park ride of the same name.
The ride sees fans take a riverboat ride through a dangerous jungle.
Disney are hoping the film will spark a new franchise like Pirates of Caribbean, which was also based on one of their theme park boat rides.
Jungle Cruise is set for release in October 2019.
