Julie Andrews - that is a well-known preprint of hers
Al Pacino - he is well known to send secretarials TTMs
Ralph Fiennes - the signature looks OK to me, but I don't know if it's a preprint/autopen/etc. Honestly I haven't paid attention to his signatures in recent years.
Ralph Fiennes sig looks good, although I do not know if he has ever used an autopen or if that is a preprint. That is indeed not a sec though.
