"12 years. Really? Wow, thanks guys for the wishes! Now back to work! Hrithik wrote on his Twitter page.
The 38-year-old actor had a dream debut in 2000 with "Kaho Naa... Pyaar Hai", which was directed by his father Rakesh Roshan, who also introduced another new face, Ameesha Patel, with the love story.
"Kaho Naa Pyaar Hai" rocked the box office, but Hrithik's later releases could not ape the success of his debut movie, however, he kept growing as an actor with each film and earned praises for his performance.
After an initial dull period, he struck gold with the science-fiction "Koi... Mil Gaya", again directed by his dad. Post that he had hits like "Krissh", "Dhoom 2", "Jodhaa Akbar" and "Zindagi Na Milegi Dobara".
The actor, who is geared up for the release of "Agneepath(2012)" remake, said: "Need to make the next 12 years even better. Love always!"
