Danny Boyle's biopic of Steve Jobs has been branded ''opportunistic'' by Apple CEO Tim Cook.

The eagerly-awaited new movie about the co-founder of the technology giant stars the likes of Michael Fassbender, Kate Winslet and Seth Rogen - but the man currently in charge at Apple isn't supportive of the latest project about Jobs.

He shared: ''The Steve I knew was an amazing human being. He's someone that you wanted to do your best work for.

''He had this uncanny ability to see around the corner and describe the future - not an evolutionary future but a revolutionary future.''

However, Cook admitted he hadn't seen either the biopic or the documentary 'Steve Jobs: The Man in the Machine'.

He told 'The Late Show with Stephen Colbert': ''He was a joy to work with and I love him dearly, I miss him every day. I think that a lot of people are trying to be opportunistic and I hate that, it's not a great part of our world.''

This comes shortly after Danny Boyle said he understood more ''about film acting'' by watching Michael Fassbender and Kate Winslet on the set of the movie.

He shared: ''I learned more about film acting. Especially these two [Michael Fassbender and Kate Winslet].

''A lot of it is their mental preparation. And it's not about slavishly learning lines, though in this case it was, because of the nature of it. But the execution of it is simple, in a way.''
