Wrongly attributed to:

Alan is not the director of 'Bob's New Suit' as some websites suggest. That is Alan R Howard, an American.
Alan was not in Little Big Man - that was the American actor of the same name. Similarly, and for the same reasons, Alan was not in:
Ladybug, Ladybug
The Miracle Worker
Antigone

Alan is not and has never been a member of the band 'The Tremeloes'!

Alan was not in the film 'Ballet Russe'.

Things he is not!

An airport: The Alan Howard Airport is not named after him! Though their little video at www.alanhoward.com/ is fun if you get there online as a friend of mine did by accident!
A hairdresser - that is a different Alan Howard
The American actor, Alan Howard (see wrongly attributed to!)
A Ballet dancer with the Ballet Russe- that was a different Alan Howard too!

He is not the hedge fund manager, Alan Howard, the 'Stakanov of finance'. That is someone else!

He is not one of the authors named Alan Howard, (there is more than one and as far as I know he has not joined them!)
