Agreed, Hrithik Roshan and Aishwarya Rai are a match made in celluloid heaven.



Not all pairs, however, can possibly be this picture perfect. Nonetheless, there's something inexplicably attractive about an imperfect looking couple.



The beauty of contrasts is visible every time comedy King Kishore Kumar quibbled with the gorgeous Madhubala over paanch rupaiyaa barah aana in Chalti Ka Naam Gaadi or a wacky Mehmood coming to an elfin Tanuja's rescue in Bhoot Bangla. Not to forget, the unmistakably cute camaraderie between the roly-poly Bhagwan Dada and his chirpy co-star Geeta Bali in Albela.



Recently too, Bollywood filmmakers haven't deterred from trying out an odd combination while casting for lead protagonists. Rama Rama Kya Hai Drama, scheduled for a February 1 release, is a case in point. Here, funny guy Rajpal Yadav plays an unlikely hubby to his sexy other half, Neha Dhupia.



Mallika Sherawat and Ranvir Shorey



A sizzling albeit eccentric Mallika is just what geek-next-door Ranvir Shorey does not need in Sachin Khot's soon-to-release directorial debut, Ugly Aur Pagli.




Still, the Hot Vs Cool chemistry between these wildly opposite personalities should be worth the price of admission









Amitabh Bachchan and Jiah Khan



Ram Gopal Varma's idea of forbidden romance had its share of merits and flaws. But what stood out the most was the core aspect of Nishabd -- potent chemistry between a 60-something Big B and his unstoppable fascination with a flirtatious teenager, played by Jiah Khan.



While Varma's yarn was woven around the dramatic age difference, others like Raj Kapoor and Dev Anand had no qualms about playing older heroes to much younger debutantes like Hema Malini and Tina Munim in Sapnon Ka



Priyanka Chopra and Amrish Puri




It takes a proverbial 'kahaani mein twist' to team Priyanka Chopra and Amrish Puri as pati patni in Aitraaz.



While there isn't any chemistry between the two in Abbas Mustan's desi take of Indecent Proposal, it's good fun to watch the late Mogambo dance around Pri Chops' nail painted fingers.



Interestingly, Amrita Singh and Kulbushan Kharbanda in Smita Patil-starrer Waaris is another instance when an absurd jodi was born out of a marriage of convenience.



Raveena Tandon and Atul Kulkarni



She's the mast mast girl of tinsel town. He's everything parallel cinema stands for. Together, Raveena Tandon and Atul Kulkarni form an unexpected alliance in Madhur Bhandarkar's political drama, Satta.



This may not be another Akki-Raveena. Yet, the underlining intensity between the two cannot be denied.




Dimple Kapadia and Akshaye Khanna



Though Farhan Akhtar's Dil Chahta Hai isn't exactly an older woman-younger guy love story, it takes the possibility under consideration.



And that's how an reticently boyish Akshaye Khanna and ultra feminine Dimple Kapadia come in the picture. Too bad Farhan plays it safe and nips the romance in its bud.



Salman Khan and Sushmita Sen



On paper, they may seem like an improbable pair. On screen, they are a complete riot.



David Dhawan knew it too well while pitting a super tall Sushmita against the considerably shorter Salman in Biwi No 1. The oddball couple, nevertheless, looked fabulous dancing to the catchy beats of Chunari chunari, Ishq sona hai and Mirchey.




Encore? Absolutely.



Mithun Chakravarthy and Pooja Bhatt



This one's as bizarre as it gets. Mahesh Bhatt did the unthinkable by casting Mithunda and daughter Pooja as Gregory Peck and Audrey Hepburn for his version of the Hollywood classic, Roman Holiday. The outcome, namely Tadipaar, was expectedly terrible.



Once bitten yet not shy, Bhatt repeated the dreadful pair yet again in another blooper, Naraaz. No wonder then Pooja decided to switch to filmmaking.
