Looking forward to his upcoming film, Cloud Atlas's release, actor Tom Hanks says, he appreciates Aamir Khan's contribution to the society, and says, giving back to the society is a tough job.

Hanks was impressed, reading about the Bollywood actor in the September issue of a leading magazine, where Aamir's Satyamev Jayate show was focussed on, saying how well the celebrity influenced a change in the society, with bringing up the critical issues of the society.

Mightily impressed by Aamir Khan, Tom Hanks will be seen in Cloud Atlas with Halle Berry and Hugh Grant, which is co-directed by Lana Wachowski, Andy Wachowski and Tom Tykwer.
