Ben Whishaw has been cast in the British drama Lilting.

The Skyfall star will lead the cast opposite Cheng Pei Pei in the directorial debut of writer Hong Khaou.

Lilting follows the story of a Chinese mother (Pei Pei) who is mourning the sudden death of her son.

She is stranded as she is not able to speak English, and has to rely on his boyfriend (Whishaw), who she knows only as his flatmate.

Also featuring in the drama are Morven Christie and Andrew Leung.

Khaou said: "This film is very close to my heart. The support I've had through the mentors has been intelligent, insightful and imaginative. There was a genuine, considered care towards helping me anchor my voice and ideas."
