Guess these Bollywood Movies from their Badly Explained Plots...!

1. A guy throws tantrums, drinks excessively, and ruins his life because his girlfriend gets married to someone else. Everyone around him suffers, but somehow, he still gets a happy ending. 2. A super-sanskari man adopts a lost child and goes on an illegal road trip across borders to return her home, while somehow managing to unite two countries emotionally. 3. A dad creates a video game villain so powerful that it kills him, and then his nerdy son has to clean up the mess by bringing another video game character to life. 4. A guy friend-zones his tomboy bestie for a pretty girl. Years later, his dead wife's daughter plays matchmaker to fix his past mistakes.
