The latest movie in the action series has been hit by a number of delays as a result of the coronavirus pandemic, with Cruise - who stars as agent Ethan Hunt - and his fellow cast members now have just three weeks to complete the film.
"Mission: Impossible has been hit by so many delays, there is now a huge pressure to finish on time," a source told Britain's The Sun newspaper. "Tom and the team are tearing their hair out. Some of the crew are agency contractors and are already booked to move on to new projects. Without them, Tom will be left scratching around for replacements. And if that wasn't enough, he has his own scheduling conflicts."
The insider revealed there is one final stunt that is yet to be filmed and it needs to be completed as soon as possible before Cruise, 58, begins promotional work for "Top Gun: Maverick" which is released in November (21).
"Top Gun 2 is released in November, meaning Tom will have to start a schedule of promotional interviews soon," the insider added. "Most of the filming on MI7 is completed but there is one last big scene to be filmed."
"The stunt sees a speeding train being driven over the edge of a cliff and into a quarry. There's no way it can be rushed. The pressure is really on."
It was recently revealed that production on the blockbuster had been put on hold temporarily after at least one crew member tested positive for Covid-19.
A Paramount Pictures spokesperson said, "We have temporarily halted production on Mission: Impossible 7 until 14 June, due to positive coronavirus results during routine testing."
"We are following all safety protocols and will continue to monitor the situation."
