The actor invited all those who were part of "Lagaan" and also the teams of all the films produced under his banner "Aamir Khan Productions".
"I'm very happy to meet my entire team of 'Lagaan' after so long. The film has completed 10 years. It's so nice to meet all these people and celebrate with them," Aamir told reporters here late Wednesday night.
"Teams of all the other films are also here. I thank them that such great talents have worked with our production house and made it what it is today," he added.
A special screening of a film based on the making of "Lagaan" was also organised for the guests that included Ashutosh Gowariker, Imran Khan, Javed Akhtar, Gracy Singh and others.
In 2002, "Lagaan" was nominated for the best foreign language film at the Oscars but it didn't win the award.
Megastar Amitabh Bachchan, who was the narrator in "Lagaan", also made an appearance.
"I'm happy and proud that my name is associated with such a great actor, director and producer like Aamir Khan and with a film like 'Lagaan' that created waves even internationally," Amitabh said.
The evening also witnessed the presence of Aamir's wife Kiran Rao, who was an assistant director on the sets of "Lagaan", and his ex-wife Reena Dutta.
"I don't believe that it's been 10 years now. Today when we saw this screening, we realised that it has been so long. We are very thankful to Ashutosh and Aamir that they made such a great film and made us a part of it," Kiran said.
"It's a very unique film and you can't make such films every day. History was written when this film was made," she added.
It was reported at that time that Aamir and Kiran began dating during the shoot of "Lagaan" but the actor denied it.
"I did not meet Kiran properly that time because she was a part of a 300-plus crew, so I was not really good friends with her during that time. I made friends with her later in 2003," the actor revealed.
Aamir also ruled out the possibility of a sequel to "Lagaan". "We will not make a sequel of this film. That's for sure," he said.
