My brother Paul McWilliams, who has died aged 43 of a brain tumour, was a visual effects specialist who worked on films including Sweeney Todd: The Demon Barber of Fleet Street (2007), Sherlock Holmes (2009) and two of the Harry Potter movies (2007 and 2011). He was also part of the team that won an Oscar for best visual effects for Inception (2010).
For a period, however, Paul had another career working with children as a PE teacher at inner London primary schools. More recently he volunteered for Sports for Hope and Independence in Bangladesh, and his work with that charity led him to set up his own, Sports for Joy, earlier this year, focusing on using sport to work with disadvantaged communities in rural Bangladesh.
