The British-Indian historical drama's trailer, released online recently, has got a good response.
"Huma is a great actress. And with 'Viceroy's House' she will get a great launch in global cinema," Chadha said in a statement here.
In the film, starring Hugh Bonneville and Huma Qureshi, the actress essays the role of an interpreter to India's last British Viceroy Lord Mountbatten and his wife.
"For the role, she (Huma) had to ditch her 'Mumbaiya' accent and get into the prim and proper British one," Chadha said.
