Brandon Lee and Paul Walker come to mind. A year delay or more isn't rare, I don't think.

Speaking of Brandon, some time watch Brandon speaking about The Crow. I watched that on a special edition of the DVD and I had to watch it twice. It was as if he knew something really bad was about to happen and he was rationalizing and coping with it. I can't watch any of the crow movies that came out after his death. I don't know if that monologue is on the internet anywhere.

River Phoenix had a role (Dark Blood) that he OD'd while filming, and it was put on hold, but then eventually finished and released 19 years later.

Even without incident, many movies with heavy special effects can take up to a year to finish the final draft. I kinda suspect it's by design. Get the studio hooked and ask for more money to increase the production values to match the acting.
