I enjoy watching mystery films and fils that revolves around a crime and the solution. 
I actually just started watching those movies from action movies. Do you know where people get the idea for those movies?
Alfred Hitchcock was one of the best directors when it came to the early days of these kinds of movies. 
I think I have heard his name but what kind of movies did he produce, mystery or crime?
He directed 53 feature films over 6 decades. he mostly did mystery and horror films. 
Wow! Did he win any awards for them?
I am not sure but I know that he used soundtracks, camera angles, and heavy shadow to scare the audience. 
What is his most famous movie?
Birds was one of his most famous movies, it used a very scare soundtrack will birds attacked humans. it was a classic suspense0thriller film
Is he still alive and making films?
