Preview:Chris Nolan is adding yet more cast to his new movie.Lupita Nyong’o is now reportedly in the cast.She joins the likes of Matt Damon, Tom Holland and Zendaya.As with lots of big movies that end up boasting giant, star-studded casts, there is a period of time known as the “drip feed” casting era, where sites break word of big names signing on to the project (or at least rumored, often leaked as a way for agents to push for better deals).
