Both Dial of Destiny and Dead Reckoning had similar budgets (around $300M) and similar opening weekends (around $80M). But the reviews and audience reactions have been better for Mission Impossible. This suggests the movie will have longer legs than Indiana Jones. Undoubtedly Paramount is hoping that Dead Reckoning's trajectory will be more like Top Gun Maverick's (staggering) 5.66 multiplier and less like (say) Quantumania's 2.02 multiplier.

edit: The article also mentions that the global opening weekend box office numbers for Mission Impossible are a lot better than the numbers for Indiana Jones, at $235M (ie $80M domestic + $155M overseas) vs $130M (ie ~$85M domestic + only about $45M overseas). That said, it's difficult to compare overseas numbers without a detailed breakdown of which markets each movie opened in. Mission Impossible may have played in more countries its first few days than Indiana Jones did.

I think we've gotten too used to Marvel $100M opening weekends
