I remember, I think, being behind the scenes at the Royal Tournament, sometime in the late 1960s, and Dad ascending a ladder and someone asking if he was Trevor Howard.  As you may tell, this is an extremely vague memory, and may even be one of those lies that Mnemosyne likes to tell every now and then.  They did bear a striking resemblance to one another, although this particular pairing doesn't really demonstrate it. 

wiki trivia: Throughout his film career Howard insisted that all his contracts include a clause excusing him from work whenever acricket Test Match was being played.
