This study evaluates the impact of casting ethnically identical actors in advertisements to elicit a favourable attitude towards the advertisement and the product. Our study explores the effectiveness of cross-cultural advertising and investigates the effectiveness of advertisements. In this experimental study, a national sample (N = 252) was recruited with an equal number of Indian and Middle Eastern subjects, which were randomly chosen across the United States. The results reflect that attitude formation patterns for Indians and Middle Easterners are dissimilar when they are exposed to advertisements containing actors with varied ethnicities.
