Now, it's your turn!

1. Add your movies to the code sample and find which ones are your favorite movies.
2. Next, find all the films released in the year you were born. Fill in the body of the `WasReleasedOn` method. It should check if a movie’s release year matches the given year.
3. Then, inside the `FindMoviesReleasedOn` method, write a LINQ query to filter the `movies` collection using the `WasReleasedOn` method from step 2. 

There are some instructions as comments in the code sample below. Take your time to go through them. We are working with your answers in the following exercises and lessons.
