Changing MS access to Oracle

Question

I have to change the MS Access to Oracle.
This is the MS Access command---->
SELECT Theatre
FROM [SELECT Theatre, Title FROM Showtimes WHERE Day='Sat']. AS R
WHERE Title IN (SELECT Title FROM StarsIn WHERE FirstName='Bruce' AND LastName='Willis' AND StarsAs='actor');
I don't know how to change( especially in line 2 ---> 'FROM [SELECT Theatre, Title FROM Showtimes WHERE Day='Sat']. AS R' )
Please Help me
Thank you

Answer 1

SELECT THEATRE FROM
(SELECT THEATRE, TITLE FROM SHOWTIMES WHERE DAY='SAT') S
WHERE S.TITLE IN
(SELECT TITLE FROM STARSLN WHERE (FIRSTNAME='BRUCE' AND LASTNAME='WILLIS') AND STARAS='ACTOR')
