Actor and comedian Billy Connolly says his friend Robin Williams "tried to say goodbye", before Williams' death in August this year.

"We told each other we loved each other. I told him and he told me many times," said Connolly, in an interview with London's The Telegraph.

"I never stopped it and he never stopped telling me. As a matter of fact, I thought afterwards he tried to say goodbye to me, because he got very luvvie towards the end," Connolly said.

"It's fanciful but that's what I told myself. On the last phone call he said, 'I love you like a brother' and I said, 'I know you do' and he said, 'Are you sure you know?' and I said, 'Yes'. Robin worried about everything."
