Having done intense films like ‘Masaan’ and ‘Gangs of Wasseypur’, Richa Chadda now wants to experiment a bit with cheerful and fun films. “I am waiting to do a bubbly, candyfloss like films, because I have done a lot of intense ones now.” While she waits for the right offer, Richa will next be seen romancing Randeep Hooda as Charles. “He had some seductions, allure, something mysterious about him. And you want to spend time with him,” said Richa talking about her character in ‘Main Aur Charles’. There will be lip lock between the duo in the movie, and Richa’s character has an intense shade to it.
