It would be like asking each male actor personally: Which movies were you in when you were between the age of 20 and 30? To be clear, that would be 30 years and 364 days old.
For example, for today, this would find me actors like: Miles Teller (Whiplash), Ellar Coltrane (Boyhood), Evan Peters (Kick-Ass), Aaron Taylor-Johnson (Kick-Ass)
But of course I'd like an overview of all time, so also movie titles that had male debutants aged 20-30 in 1970 or in 1889.
I think this would involve some query that compared Actor-Birthdate to Movie-Shooting-Date.
This might be conceptually as follows:
IF **Actor-Birthdate** -/- **Movie-Shooting-Date** > 20 but < 30
then give **Movie-Name**.
This query or algorythym or function has to be performed on every single male actor, I guess.
I would need actor datasets with their D.o.B, the movies they made and the film shooting dates of those movies.
I suppose the IMDb site itself does not offer tools to do this, so I guess it would have to be imported into some database program like SQL or Wandora. Or Excel or MS Access
I'd be very happy if anyone had any idea how to do this.
