Explanation
This query is selecting the first and last names of actors who have acted in the film 'AFRICAN EGG'. To do this, it's joining three tables - 'film', 'film_actor', and 'actor' - using the 'film_id' and 'actor_id' columns. The 'WHERE' clause is limiting the results to only show actors who have acted in the film 'AFRICAN EGG'.
