Now to answer the question: Is M. Night Shyamalan in all his Movies?
Well, the short answer is “no, but he does in most movies.” However, I’m not going to leave it by that because I probably know your next question which is “in which movie did he made an appearance?” Now, I will also give an answer on that one by listing every movie down below and tell you if he was in it or not. In addition, I will include which role he played.
The films listed are only movies he directed. So films like Stuart Little where he co-writed the script won’t be included.

The truce is broken and the village is increasingly threatened by the creatures.
The Village has been misconstrued by many people and as a result is often watched by the wrong audience or with the wrong intention. The film was promoted as a horror film, but M. Night himself has admitted that The Village is not a horror. It is more of a romantic drama with horror elements, rather than the other way around. The poor promotion made for a successful opening weekend, but after that, the film’s revenues were low.
