Movie One, Sunday, 8.30pm ★★★ This clever thriller has its ‘‘what ifs’’ in order. What if a drug could activate that fabled 90 per cent of our brains we never use? What if a daily pill made you a mastermind? Once poor writer Eddie Morra (Bradley Cooper) parlays his addiction to fame and fortune, the race is on to find more tablets. Co-stars Abbie Cornish, Robert De Niro.
