Komunikasi antarbudaya dapat menjadi salah satu alasan di balik banyak fenomena budaya yang menarik, sehingga tema komunikasi antarbudaya sering digunakan dalam film, seperti dalam film Monsieur Lazhar yang bercerita mengenai seorang imigran Aljazair yang baru saja pindah ke Kanada untuk mencari perlindungan karena telah terjadi penyerangan terhadap keluarganya di negara asalnya. Melalui uraian aspek naratif film serta dengan teori efektivitas komunikasi dari Joseph DeVito, didapatkan kesimpulan bahwa komunikasi yang terjalin antara imigran Aljazair dan warga Kanada dalam film adalah suatu komunikasi yang tidak efektif.

Intercultural communication can be one of the reasons behind many interesting cultural phenomenon, so the theme of intercultural communication is often applied as a theme in the film, as in the film Monsieur Lazhar which tells the story about an Algerian immigrant who recently moved to Canada to seek refuge because there have been attacks against his family in his home country. Through the description of the narrative aspect of the film as well as the effectiveness of communication theory of Joseph DeVito, it was concluded that communication between Algerian immigrants and Canadian in the movie is an ineffective communication.
