In Hollywood, the famous adage of 'you're only as good as your last performance' still rings true.
Actors can go from being !*$% of the walk in a Marvel film to a cinematic laughing stock in an ill-advised family 'comedy' - looking at you Robert Downey Jr - and their reputations can be seriously damaged in the aftermath.
But, they aren't the only talents in the movie making business who are in danger of becoming yesterdays news off the back of an unmitigated disaster. Directors are also liable to slip into obscurity if a high profile project crashes and burns either critically or financially...or both.
Equally, if said picture does well and becomes a resounding hit, you can bet that very same director's stock will rise.
Some ambitious projects represent a chance to become a household name and set yourself up for life. Yet, things don't always work out that way and a once promising or esteemed director can be left picking up the pieces of their legacy if that great risk doesn't pay off with a great reward.
Fingers crossed it all works out in the end, but these next projects could very much be make or break for this set of hopeful helmers.
10. Jason Reitman - Ghostbusters: Afterlife
Let's face it. Ghostbusters 2016 was an absolute disaster. But, that's not exactly breaking news, is it?
However, when Ivan Reitman's (the original Ghostbusters director) son Jason Reitman agreed to helm a soft reboot of the franchise in 2019, fans' heads were definitely turned by the decision to mask over the recent flop so soon after its release.
Bringing back original cast members such as Dan Aykroyd, Bill Murray, Sigourney Weaver, Ernie Hudson and Annie Potts, definitely hinted at this project trying to get back to the roots of what made the first two Ghostbusters film so beloved. Newcomers such as Paul Rudd and Finn Wolfhard also added some fresh feel-good talent into the mix for good measure.
Yet, there's no escaping the fact that if this upcoming attempt to recapture the magic falls flat on its face, the Ghostbusters franchise may well and truly be finished for good and with that so too could be the blockbuster aspirations of Reitman.
He's obviously an extremely talented director - his work on Juno and Up in the Air highlight this - yet Ghostbusters: Afterlife is a high profile risk that could either see him become Hollywood's new go-to big budget comedy guy or see him ushered quickly back into the lower budget bracket.
