Lenfilm is a movie studio in Russia that makes movies and TV shows. It's like a big building where people work to create videos that we watch on our TVs or computers.
When someone has an idea for a movie or TV show, they write it down and then lots of people work together to make it happen. They use cameras and microphones to record the actors and actresses saying their lines and doing things in front of the camera.
Once they have all the footage they need, they use special computers to edit it together into a finished movie or TV show. They add music, special effects, and other things to make it look and sound really cool.
Then, when it's all finished, they can show it in movie theaters or on TV. People all around Russia and other parts of Europe can watch the movies and TV shows that Lenfilm makes.
