Prepositions after verbs

Portray in, portray by or portray as?

Portray as is the standard pattern for describing how someone or something is represented. In and by usually belong to surrounding information, not to the verb itself.

Quick answer

Which construction is most natural?

Use portray as to describe the role, image, or identity presented. Portray in usually introduces the medium or location. Portrayed by identifies the actor in passive clauses.

The film portrays him as a hero.
The character was portrayed by a famous actor.
