The 45-year-old filmmaker took to micro-blogging website Twitter to share his emotions with his fans.
"I'm in a very seriously transitional space right now as JAZBAA is getting over and I'm beginning to get into my next," he tweeted.
Gupta feels that he is going through mixed emotions as his one film is ending and "the other" is beginning.
"One film ends the other begins. Can't let go of one, can't wait to start the other. Seriously mixed emotions," he added.
`Jazbaa`, which is being touted as actress Aishwarya Rai Bachchan's comeback wagon, also stars Irrfan Khan, Shabana Azmi, Abhimanyu Singh, Atul Kulkarni and Chandan Roy Sanyal. The film will hit the screens on October 9.
