I guess the Studio had better shoot a new Scene for the upcoming Movie where his Character gets killed off.
Can’t let this upset the future Movie Franchise Releases.
It would rival what happened on the TV Show Bewitched where Darren was replaced and everyone acted like nothing changed.
They will probably get a new Chekov and act like nothing has changed.
There have been other cases where new actors take the place of old ones. John-Boy Walton comes to mind. They had a new John-Boy for a while. They had a new replacement Becky on Roseanne Barr’s show. It happens. Chekov was a major character so I expect they will replace him, not have him get killed off.
