Johnson promises his boat ride to be the cheapest yet the most thrilling for he is to take them through places infested with aggressive jungle natives. What adds a twist to their journey is a competing German expedition.
Set in the early 20s and shot in some exotic locations, it is to be seen if Blunt, her brother and Johnson make it to the magical tree or not.
Spanish filmmaker Jaume Collet-Serra has directed the film inspired by the famous Disneyland theme park ride.
Apart from Blunt, Whitehall and Johnson, also starring in the film are Edgar Ramirez, Jesse Plemons and Paul Giamatti.
The film is bankrolled by Johnson along with John Fox, John David, Hiram Garcia, Dany Garcia and Beau Flynn.
'Jungle Cruise' is set to hit big screens on July 24 next year.
