Tim Peake doesn't tend to worry too much about scientific accuracy in space movies, despite having spent his share of time in orbit.While many experts in their fields are critical of fiction's desire to embellish and distort, Peake told Yahoo that he is 'there to be entertained'.He has now made his own journey into the world of sci-fi movies with a cameo as the voice of mission control in Pixar animation Lightyear, in which Chris Evans plays Toy Story character Buzz.Lightyear is in IMAX and UK cinemas from 17 June.
