Often sequels result in a change of stars even if the main order remains undisturbed. It adds a new zing to the franchise while retaining its original feel.
And so while it's confirmed that Abhishek Bachchan and John Abraham will feature in Dostana 2, Priyanka Chopra bids adieu to make way for, reportedly, Kareena Kapoor or Katrina Kaif.
Also, remember Dhoom 2, which had Hrithik Roshan stepping into the anti-hero shoes of Dhoom's John Abraham?
Here's looking at a wish-list of possible sequels and the stars we'd like to see cast in them:
Shahid Kapur and Priyanka Chopra's twins grow up to tell their own story. How about Ranbir Kapoor channeling his inglorious side this time around? It would be a welcome break from all the endearing Sids and Prems, no?
Quick Gun Murugan 2
After Priyanka Chopra, we would love to witness Sonam Kapoor discovering the not-so-glamorous side of high-fashion.
The recently crowned best-dressed actress with her astonishing know-how on all things designer would be perfect for the part.
Andaz Apna Apna 2
Knowing Amar and Prem and their flexible moralities, they'll only be too happy to have a brand new set of Raveena and Karishma to woo.
And so Aamir and Salman Khan return to their 'Haila-Ooimaa' ways with Priyanka Chopra and Kareena Kapoor in mind. Wonder how Crimemaster Gogo will react to that?
Love Aaj Kal 2
The definition of new age relationships is hard to come by. And so another modern-day romance, across a couple of continents, unfolds through a couple trying to come terms with what they share/could share.
It would be interesting to watch the chemistry between two powerhouse actors Aamir Khan and Vidya Balan engaging in some witty and compelling When Harry Met Sally-ish banter.
Salman Khan made utterly implausible sequences work in Boney Kapoor's cheesy action caper.
Which other actor can accomplish this rare feat? Sunny Deol? Too old! Hrithik Roshan? Too classy!
Tell you what, let's retain Salman and replace Ayesha Takia with Deepika Padukone. Untried combinations are seldom boring.
Post-Govinda, Love Guru Salman Khan finds another quirky, lovelorn client to cope with. And who better than buddy Sanjay Dutt to do the honours?
Besides, the man can be goofy, amusing and shares a cool camaraderie with Sallu.
There's a new con man in town. And it's not Abhishek Bachchan.
Assuming that Bachchan Jr gives up his tricky ways to settle down with a certain Piggy Chops, we cast a charming Saif Ali Khan as the latest Mr Fraud on the front. Bebo approves?
