A fortnight's passed since the questions were put on board. Thanks for the responses, Prit and Vas.
Here are the answers.
1. PERL
2. K(C)andy - that's a hell of a connect, Prit. Didn't think of that, actually. Twix is manufactured by Mars which used to be M & M not a long time ago and they still make the M & M bars. Luckyland Biscuits is owned by Murali's dad. Now, the media've already begun to call Murali & Ajantha Mendis as M & M. So, M & M was my connect.
3. Ride of the Valkyries by Richard Wagner features in these films. (What's Opera, Doc ? is a 1957 animated short featuring Bugs Bunny & Elmer Fudd at an Opera. So the pun on What's Up (or Op) Doc ?)
4. Mark Twain came up with this quote. Correct. This is another one that's rebounded on me. The answer I was looking for was Orkut Buyukkokten's home page.

5. The Joker. Cesar Romero played The Joker in the 1960s comedy series. Nicholson played The Joker in Tim Burton's Batman (1989). Mark Hamill (Luke Skywalker) voiced him in the animated series of the 90s. Heath Ledger's just made any further renditions by other actors pointless.
6. William Tell
7. The Watchtower Group is right. A better answer would've been Jehovah's Witnesses.
8. Michael Phelps (MP)
9. Red Baron (Manfred von Richthofen) with his uncle Ferdinand von Richthofen who coined the term Silk Route shown in the map.
10. Vas. Chipko Movement - bull's eye. Let me expound on the individual pics though.
The 3rd pic (clockwise) shows Guru Jambheshwar (Jambhoji) who is revered / worshipped by the Bishnois cult. The Bishnois worship nature nature and were in the news when Salman Khan shot a Black Buck. The Black Buck (in particular) is a revered animal among the Bishnois cult.
The 2nd Pic (the monument) shows the cenotaph of Bishnois who laid down their lives at Khejarli in 1730 AD in order to protect trees from being chopped by the men sent by Raja Abhay Singh (ruler of Jodhpur). Nearly 365 Bishnois are believed to have died. This gave birth to the Chipko Movement.
The 4th pic shows the way the Bishnois would hug trees while becoming martyrs and this was adopted by the Chipko Movement as their unofficial motif.
The 1st pic shows Vandana Shiva, who was the voice of the non-violent Chipko Movement of the 70s. She is now one of the leaders of the International Forum on Globalizaiton.
The connect - Chipko Movement
This page will feature the next quiz soon.
