The film's team finished the last day of the shoot in Manali and Sircar says they will celebrate it with a small party.
"Yes, there is a party. It is really cold in Manali and we have have an early morning flight to catch. We are happy and relieved that we have finished the shoot before time," Sircar told PTI over phone.
The director, best known for his films such as 'Vicky Donor', 'Piku' and 'Pink', says 'October' will explore a different side of Delhi.
"I find a lot of character in Delhi. I am familiar with the city and the people. It is always very comforting to return to Delhi. I will explore the romantic side of the city this time."
The director has teamed up with Varun for the first time and is all praise for the actor.
"I think he is very bright. He is trying to open up to different genres. Actors should keep exploring different genres, stories and directors. At the end of the day, you have to challenge yourself."
He decided to cast Banita after directing her in one of his commercials.
"It just so happened that the ad turned out to be really good, and we found the character that we were looking for in her."
Sircar's producing partner Ronnie Lahiri said they would release the film on April 13 next year via their company Rising Sun Films.
"There is not much gap between shooting and the release as we did not want to delay the release as we have a good film in our hands, and there is no point in waiting."
Lahiri said they finished the shoot in just 38 days and ahead of schedule.
"We loved collaborating with Varun. It was a great atmosphere on the sets. It was never pack and to my room for Varun. He would usually hang out with the crew."
Varun also tweeted about the wrap of the film, sharing pictures with the team, using rhyming words in the caption.
