Rana Daggubati has confirmed he will be replacing Nana Patekar in 'Housefull 4', after the latter walked out of the project following sexual harassment allegations against him. "I've never been part of a genre like 'Housefull' and it's...exciting to work with different genres," he added. Rana further said he's looking forward to working with Akshay Kumar and producer Sajid Nadiadwala.
