Have a Bolly good time III

Okie dok, so here's the third of the Bollywood A to Z quizzes. The theme for this one is sibling rivalry, which actually makes the quiz relatively easy to crack. See if you can identify A to Z?

A and B are siblings who have starred in a couple of movies together, though A is obviously more successful than B. B is married to C who has also appeared in many movies, though never as a lead. C's sibling D has played in the lead, but has failed to make the impact that C has. D's best friend E has also made a successful career in Bollywood and is the pioneer of a recent and much-aped body-related trend. E's sibling also did well in the industry, even winning a national award for the movie F. F was directed by G, who worked for his sibling H in his early days in Bollywood. G has won multiple awards and there is even a lake named unofficially after him. G's kids I and J are also part of the industry, albeit in different fields. I has made a mark while J is still struggling (and has probably given up by now). J's debut movie was K, which was also the debut movie of L. L's career did not really take off but sibling M is a successful star, and has even made some waves abroad. L also tried out television but did not meet any success. The same television show also featured N in another season. N's Bollywood career never really took off, but the name N features amongst Bollywood's top MMS scandals. N's sibling O made a sensational debut in the movie P directed by Q. Q's sibling R also happens to work in Bollywood, though in a different line. P featured a popular dance number choreographed by the very successful S, whose sibling T is associated with comedy movies. The first movie S choreographed in was U, featuring V in the lead. V's sibling also featured in a few movies alongside his brother, and even tried his hand at a leading role, but without success. V acted in a ground-breaking movie directed by W whose sibling X is also a filmmaker. X's last movie Y with W in the lead, featured Z in a cameo. To close the loop, Z is so not friends with A anymore.
