Father and son duo Will and Jaden Smith promote their new film, After Earth, in Russia and talk about their family business. The father and son duo posed for pictures on a city rooftop overlooking St. Isaac's cathedral before giving a news conference to local journalists.

Despite working together constantly, the pair had nothing but praise for each other, Will said: 'I think Jaden is very disciplined. He is extremely hard-working and if there was something that people don't know about Jaden, I think it is how hard that he works.'

After Earth is set for release in June of this year. .
