Incomplete lesson?

Question

Why is “You remind him of Audrey Hepburn." ? Translated into “Tu lui rappelles Audrey Hepburn.”

Isn’t it missing an “à” as per lesson guidelines? Shouldn’t it be “Tu rappelles Audrey Hepburn à lui”?

Accepted Answer

The lesson does cover this - have another look at the use of indirect object pronouns section.
It is only expressed as  ‘à qqn’, when ‘qqn’ is represented by a noun/name. Once you introduce a pronoun to be the ‘qqn’ as the indirect object, it takes its position before the verb as an indirect object pronoun, as in the standard usage and word order in French. 
Eg “ Tu rappelles Audrey Hepburn à Pierre. Oui, c’est absolument vrai. Tu lui rappelles Audrey Hepburn. “
