I was watching the opening credits sequence, and noticed some movie billboards up behind the Helen Poster.
Quiz # 1: Which 4 films are being displayed on billboards in the background of the Helen credits? (I already found Abhinetri)
1. Upper Left - Abhinetri
2. Upper Right - ???
3. Lower Left - ???
4. Lower Right - ??? Starts with "B"?
You can also checkout the opening sequence itself.
Hope you can figure it out!
