This is truly Singh overload…everyone is pretty much called Singh 
Gone are the days where you would have a Sardar fly overseas to become a cab driver. Now they go Down Under and become dons! 
. Lucky Singh(Sonu Sood) left home to become the undisputed “King” of the Australian underworld. This means he’s constantly dodging enemies and making headlines causing much embrassement and shame to people in his village. The villagers are also tired of Happy Singh(Akshay Kumar) who has a heart of gold but his helping anyone often results in property destruction all around 
So they decide to send Happy and his best pal, Rangeela(Om Puri) to Sydney to make a honest man of Lucky and bring him back home. But Happy being Happy lands up in Egypt instead and runs into Sonia(Katrina Kaif) whom he instantly falls for. But alas Happy must goto Sydney first before he can pursue the woman of his dreams…but not before a quick song n dance routine
Happy and Rangeela finally land in Sydney and try to convince Lucky to return home. All they get for their trouble is to get thrown out on the streets. A homeless Happy runs into a desi Rose Lady(Kiron Kher) whom he treats like his mother. But mummy dearest is depressed ‘coz her daughter is coming back home after finishing her studies with the boyfriend in tow. The downside is the daughter thinks they are well off but mamma is just managing to scrape ends together. So in true Happy style the man comes up with a hare brained scheme to help Rose Lady out. Only to discover that the daughter is none other than Sonia!! And her boyfriend is a snooty rich kid, Puneet(Ranvir Shorey)
Singh is King is very very Punjabi and rather over the top. Director Anees Bezme does manage to steer away from blatant slap stick though sparing us yet another Welcome.
Akshay Kumar truly proves he is the brightest star in Bollywood today. The movie survives simply because of him. Sure there are times he gets on your nerves but he grows on you. His charm is undeniable.
Om Puri excels as Rangeela plays the perfect foil to Happy. Certainly not his career best but it’s wonderful to see him in form again after moronic roles like Mere Baap Pehle Aap.
Sonu Sood does well as Lucky though he doesn’t have too much to do.
Katrina Kaif…well she’s pretty as a picture and her smile will make u melt. The flat dialog delivery and the accented Hindi continue though. For someone being touted as Bollywood’s reining queen she sure can’t act.
Neha Dhupia palying Lucky’s sidekick does well in the brief role.
Ranvir Shorey is fabulous in his super short role. Truly there is no role this man can’t do.
All in all this is Kumar’s show all the way.
And it’s wonderful to see all the Sardar’s dressed so wonderfully after Daler Mehendi’s flashy outfits.
Go ahead and grab some popcorn
