she loves "excessive work".
After Heaven On Earth, she will move on to her next project Stella, a comedy, from Feb 20. Although her brother is directing it, she will have to assist him.
Narrating the tight schedule, Mehta told IANS: "I woke up in Chandigarh last week wondering where I was. I'm now in Delhi with my mother. And I'm trying to gather myself together.
"We rushed from location in Toronto straight to the airport because we had dates for Preity only till Dec 24, 2007. We arrived at Delhi at 3 a.m. and caught a train to Chandigarh and started the rehearsals.
"My god, I didn't know where I was. But, you know what? I love this excessive excitement. Every film is a pleasant challenge."
Talking about Stella, Mehta said: "Actually, my brother Dilip is directing Stella. I'm helping him out. Then I move on to my next project Luna with John Abraham, Rachel Weisz and Dustin Hoffman.
"In Stella I'll work again with one of my favourite actresses Seema Biswas. She's amazingly funny if she wants to be. We're shooting Stella in Delhi. It'll be a bilingual in Hindi and English. Then I move to San Francisco for Luna."
Mehta has to leave for pre-production of Luna in February.
"After Luna, I've another Hollywood project entitled Land Of The Morning Calm. That's Korea in Korean."
She's become as prolific as David Dhawan, I joked.
"Ha, ha, I love David Dhawan. It's so strange that I should be working so much. But everything happens at a certain time. In 2007, I took time off because my dad passed away and I needed to be with mom. The loss of a parent is something one can never get over.
"I immediately got into Heaven On Earth. I had such a good time shooting it. Though it's on a serious theme, I had a blast doing it."
Mehta, who has wrapped up her work with Preity, is all praise for the actress.
"Everyone on the sets just loved her. She's a real trouper - warm, alive and courageous. And she has amazing talent."
For now she is happy to spend some precious time together. "We play rummy all day long. That's the Punjabi side of me."
