I believe this movie was a thriller about a production set plagued with suspicious deaths during filming of the production.
I remember watching this movie years ago on late night TV. It seemed to revolve around a group who were working on a movie (a movie within a movie). Along the filming of this movie members of the cast/crew start dying due to suspicious accidents on set. The protagonist with a supporting actress begins to connect the dots and they come to realise that there is actually a killer among the crew.
I faintly remember the final scenes where the killer gets his comeuppance. The actor and actress are on a boat in the ocean. This might have been a scene from one of the prior accidents/deaths. The actress realises there is a clue under the water (possibly a sunken wreck) and dives into the ocean to retrieve it while the actor keeps an eye out on the boat above. He hears a plane nearing their position but does not realise the killer is flying so he dismisses it and averts his attention back to await the return of the actress who is still underwater.
I guess she finds what they were looking for and heads back to the surface to report her findings. At this point the actor sees the aforementioned plane (revealed to be a seaplane) positioning to land on the water and he now realises it must be the killer who has come to to tie up lose ends. As the killer lands on the water the actress emerges to see this seaplane rapidly approaching her position. The plane was still carrying a lot of momentum from the landing and is gliding across the surface of the water to her position at great speed. She does not have enough time to react to the impending threat and is dispatched as one of the skids (floats) from the plane collides with her head.
This leaves only the actor on the boat and killer. Unfortunately for the killer, the plane collision with the actress causes the seaplane to go into an uncontrolled tumble across the waterâs surface while he is still strapped in. The tumbling stops near to the boat occupied by the actor and the seaplane then begins to sink beneath the water with the windshield facing up towards the waters surface (camera).
In the killerâs final moments the actor takes a vantage point above the rear of the boat staring at the killer beneath the water who is now helplessly trapped. The killer realising his deadly predicament stares up to the actor (camera) above the water.
The killer is unable to unstrap himself from the seat and begins to fruitlessly bang against the inside of the windscreen with his fist in an attempt to escape the sinking plane but he inevitably drowns in short time. The viewers (actor) get a view of his now drowned face as he and the plane continues to gradually sinks further away from the camera till we get a cut back to the protagonist bringing the scene to an end. If I remember correctly the killer had fractured his clavicle in one of the earlier filming related accidents to avert suspicion from himself. One of his arms might have been suspended in plaister mitigating his ability to be able to easily escape the sinking plane fast enough.
I believe I was early teens or younger back then and cannot remember the names of the stars but hopefully my limited description may ring a bell for someone. I tried ChatGPT but did not have much luck. Thanks for your time.
