Have a Bolly good time II

I had so much fun cracking the A-to-Z Bollywood quiz that I decided to try my hand at designing one myself. It also looks like many of you bewdas also went nuts over it. Do try the one below. It's my first and I decided to start off with something relatively simple. I think many bewdas will be able to easily crack this. If all goes well, I'll make this a regular flavour at the bar next year. I may need to ban two-time champion bewda/bewdi Sandwalker from these quizzes though. ;)

PS: Don't read the comments section if you want to try solving it first.

Movie A almost featured popular Bollywood star B but the role of the phenomenally popular character C went to D instead, reviving his career. D's close relatives E and F played mother and son in a movie G. G also featured H whose son went on to marry D's sister. H's son also starred with D in a hit movie I, which featured an iconic song J sung by ghazal maestro K. This movie was directed by a famous director L whose relative M is known for the rather liberal use of a certain set of facial muscles. M's cousin N shot into notoriety by featuring on a controversial magazine cover. N won the Filmfare Best Female Debut award for her role in the movie O even though technically her first movie was P, both directed by L. O also featured talented actor Q in a prominent role. Q, who has won the Filmfare Best Comedian award multiple times, received critical acclaim for his convincing portrayal of an old man in movie R, also directed by L. He was also part of one of the biggest Bollywood hits of all time S, directed by T and featuring U as one of the leads. U's relative V, rumoured to be headed for the altar with T, was the lead in a movie opposite talented and popular superstar W, where W sang a chartbuster X. W also acted in a very long movie Y, opposite Z. To close the loop, Z was the female lead in A.
