Isaac Asimov almost certainly never imagined his cerebral short story collection "I, Robot" would one day become a blockbuster movie, but thanks to the chemistry between Will Smith and Alan Tudyk, who voices the rogue robot Sonny, it absolutely works. Smith stars as Chicago homicide detective Del, who hates and mistrusts robots, which makes him an interesting choice to spearhead a case where a robot is suspected of murder. However, nothing is as simple as Del suspects, which he realises when he meets Sonny, a robot who is capable of defying the Three Laws of Robotics, but who is still nowhere near as nefarious as his creators.
