How Disney Should Make Indiana Jones 5

9. Keep It Grounded Where Possible

There are lessons to be learned from how the nuke-proof refrigerator and computerised aliens went down.

Indiana Jones, for the most part, should remain grounded by embracing real locations and set pieces that evoke its pulp movie roots without descending into parody.

The series has always been about stumbling upon pockets of mysticism within the real world, but Crystal Skull's introduction of other worlds and planets clashed with its lore.

The audience is willing to suspend its disbelief when light fantasy elements are thrown into the mix because the universe the franchise exists within is otherwise credible. Adding flying saucers to the equation compromised this.

The first three Indiana Jones movies walked a tightrope between thrillingly plausible and over-the-top where its trademark action set pieces were concerned, yet Crystal Skull found no such balance and plunged into the chasm below.

Stick to the ancient temples and historical backdrops, and avoid the temptation to ride motorcycles through college campuses and nuke household appliances.
