If you want to see Tom Cruise reprise his role as secret agent Ethan Hunt then word around Hollywood is that you better pony up the ticket price to see Cruise's latest film, Knight and Day. If that film flops, Paramount may drastically alter their plans for the fourth installment in the Mission: Impossible franchise.

Reports state that Paramount executives are concerned about the opening tracking numbers for Cruise's latest action film and are hoping the five day totals are respectable (which seems more like a dream than a realistic hope given that the opening day tally for the film was a paltry $3.8 million). Meanwhile, the script for the fourth installment in the M:I franchise has just been turned in, and Brad Grey and Rob Moore are in the process of trying to determine that film's preliminary budget. If Knight and Day underperforms, the thinking is that Paramount will either scrap M:I4 completely, shift the focus of the film to Hunt and Shia LaBeouf a younger agent, or cut the budget dramatically. None of those things seems to bode particularly well for Cruise or the studio.

Hit the jump to find out which of these options is most likely to happen and how it will impact the future of the Mission: Impossible franchise and Tom Cruise.
