The 37-year-old made his debut with J.P. Dutta's 2000 movie "Refugee", which also marked Kareena Kapoor's entry into filmdom.
"So, it's been 13 years to the day since my 1st film 'Refugee' released - 30th June, 2000. It's been a fun ride so far... Thank you all for the immense love, faith, belief, support and tolerance. I would not be here without you! Big love," Abhishek posted on Twitter.
"Memories of the premiere of the film are still so vivid. The great Liberty cinema, almost the entire film industry, the media. And amidst all this pageantry and excitement, two very scared, nervous and hopeful debutants, Kareena and myself. Great memories," he added.
So far the actor has been part of 50 movies, including hits like "Yuva", "Dhoom", "Bunty Aur Bubli" and "Bol Bachchan".
"13 years and just about 50 films, not bad! It's been a lot of fun. But not as much fun and promise that the coming year thes hold," he posted.
Last seen in Rohit Shetty's "Bol Bachchan", Abhishek will soon be seen reprising his role of ACP Jai Dixit in the third instalment of "Dhoom" franchise, which also features Aamir Khan and Katrina Kaif.
