In the time travel film About Time, Tim's father James tells him that all the men in the family can travel backwards in time to any point they have experienced.
James lives with Uncle Desmond, who isn't directly said to be a family member, but having the Uncle title we are led to believe he is a family member.
There is no mention as far as I am aware that Desmond can travel through time.
Is this mentioned or alluded to in the film or has any production material become available that confirms or denies that Desmond can travel through time.
