Misión: Imposible - Sentencia mortal. Parte Uno

The frequent delays caused by COVID-19 ballooned the budget to $291 million, making it the most expensive Mission: Impossible film (surpassing Fallout, $178 million), the most expensive film of Tom Cruise's career (again surpassing Fallout), and the most expensive film ever produced by Paramount (surpassing Transformers: El último caballero (2017), $217 million). The insurance company Chubb originally gave Paramount only £4.4 million (about $5.4 million) for the delays, arguing that the cast and crew could still fulfill their duties to the production despite being infected with COVID-19. Paramount sued Chubb in 2021, and the two companies settled in 2022. In 2023, Chubb gave Paramount a £57 million (about $71 million) payout for the COVID-caused delays, reducing the film's budget to about $220 million, which still makes it the most expensive film for Cruise, Paramount, and the franchise.

Steam trains, especially moving at high speeds, need to be continuously provided with fuel, in this case coal. With the engineers killed and the controls opened all the way, the locomotive would have gradually slowed down and come to a halt as the pressure in the boiler dropped. That train would never have reached the bridge for that distance with no coal provided.

Since the early 1900s, when firebox coal consumption exceeded the efforts of two men, the trains have used mechanical stokers. The coal would continue feeding without one missing coal shoveler.

Disclaimer as one of the last entries in the end credits scroll: "The Producers wish to express that in no way, shape or form were the Rome Spanish Steps used to drive a moving vehicle down. This segment of the film was re-created with a set built on a Studio backlot."
