Website Comic Book Ressources ask their readers a question every week and their blog sketch artists will pick some of the suggestions and post a drawing in the "The Line It Is Drawn!" section.
This week topic was :
Dream casting! Pick a famous actor that you’d like to see portray a comic book character and our artists will draw said actor/actress as that character. What would a Clark Gable Superman look like? Or a Michael Caine John Constantine? Stuff like that.
