The movie must have some pretty serious problems indeed if it needed changing after filming began.
Any and all forms of writing are fluid and dynamic until publishing (or in this case, theatrical release). In some cases, it remains fluid and dynamic after the original release and is released again later in a new form.
No draft of anything is ever perfect. There are always changes to be made. Maybe you wanted a character to vault over something, but the actor can't do it and you don't want to use a stunt double. So you change something, either the scene writing or the prop, to allow filming to continue. That's just an example, obviously.
