Elegance is in the eye of the beholder, but...:

This may not match *QUITE* what you want -- if the honorific or
any part of the name but the last ever ends with a capital, this
may unwontedly match it.  It may be best to stick a word-boundary
marker before that initial:

match_initials = re.compile(r'(\b[A-Z] )+')

Anyway, now add:

def nospaces(matchobj):
    return matchobj.group(0).replace(' ','')

This then becomes:

for director in directors:
    new_director = match_initials.sub(nospaces, director)

plus of course whatever "print"s you want.
