Saif, Shah Rukh, Hrithik, Salman: THEN and NOW!

A decade or two in a person's life makes a world of a difference.

Case in point: Our Bollywood stars, who've been around since the 1990s and continue to rule the roost.

Starting with Saif Ali Khan, we look at the top actors of today, and how different they look from their younger, 20-something selves!

Saif Ali Khan, who completed 20 years in the Hindi film industry last year, made his debut with Yash Chopra's Parampara in 1992, costarring Aamir Khan.

While the Nawab of Pataudi, 42, looks as dapper as ever, the boyish charm and sharp jaw has given way to a more rugged look.

Irrfan Khan has come a long way from his days of obscurity to mainstream success.

Although he made his acting debut with Mira Nair's Salaam Bombay, the actor rose to fame with Tapan Sinha's award-winning 1991 film Ek Doctor Ki Maut.

Twenty-two years later, the actor flaunts his new-found swagger in Tigmanshu Dhulia's Saheb Biwi Aur Gansgter Returns.

Sanjay Dutt made a successful debut in father Sunil Dutt's Rocky as a doe-eyed youngster -- quite a far cry from his present burly appearance as a 53-year-old.

Jumping on the bulk-up bandwagon, Aamir Khan is but a mere shadow of his 22-year-old self from his Qayamat Se Qayamat Tak days.

At 47, he sports short hair and a scowl as a troubled cop in Reema Kagti's Talaash.

One of the most good looking leading man of his time, Salman Khan was probably headed towards the romantic boy route until he decided to bulk up.

While his leaner frame in Maine Pyar Kiya had the nation swooning, his Chulbul Pandey is just as popular.

Sunny Deol, who will be seen next opposite a much younger Kangna Ranaut in I Love NY, looks quite different from his younger self from Betaab.

The most prominent change one will notice about Shah Rukh Khan's appearance is the absence of his famously floppy hair that he wore proudly in quite a few of his early films like Deewana.

He cuts a clean contrast with an armyman look in Jab Tak Hai Jaan.

Hrithik Roshan seems to be moulding his looks to lose the soft, boyish features from his Kaho Naa... Pyaar Hai days, and add on a way more macho look, like in Agneepath and his upcoming film, Krrish 3.

In the 1991 Raj Sippy film Saugandh, Akshay Kumar debuted with overgrown hair and a tiny earring.

Cut to 2013: We have an ever youthful Kumar playing a conman with much finesses in Special Chabbis.

From the intense action hero of films like Phool Aur Kaante, Ajay Devgn has tranformed himself into a champion of oddball comedies.

A stark difference, this.

Who knew one of the best dancers of his time would pile on kilos in the later part of his career?

A much younger and thinner Govinda from Love 86 is almost unrecognisable in his Partner avatar.

John Abraham's perennial state of undress and long hair have given way to casual tee shirts and a stylish crop.
