Stars Who Passed Away While Filming And Had to Be Immediately Replaced
With today's technology, you can age, de-age or include an actor who wasn't present when making a movie. Some examples include The Curious Case of Benjamin Button, The Irishman and a handful of films in the MCU. Sometimes, they can fool not just the audience but those working on the film.
During the post-production of Rogue One: A Star Wars Story, the crew was labouring over the digital recreation of "Governor Tarkin". Another employee, not too familiar with Star Wars, asked why they were so concerned with the actor's skin and lips, not realizing that the character on the screen was a product of CGI. Sometimes, special effects are needed if a main actor passes away during the production of a movie. To hear about such examples, please watch the video above.
