This study examined the potential of entertainment-education (E-E) for promoting engagement with a science issue. It was assumed that certain entertaining features of a media experience increase viewers' perceived knowledge about an issue. Drawing on different theoretical models of E-E and on persuasive effects of narrative media messages, three hypotheses and one research question were assessed in a survey among 103 participants, who were shown a movie about genetic engineering beforehand. Results suggested that the higher viewers' transportation, identification, and enjoyment were, the more they actually felt informed. Viewers' degree of transportation, though, revealed to be sufficient to explain their perceived knowledge.
