When it comes to describing the male protagonist in a movie, book, or play, the term "leading male" may seem a bit overused. Luckily, there are plenty of synonyms to use instead. You could refer to him as the "male lead," "hero," "protagonist," "star," or "main character." For a more specific description, consider using terms such as "alpha male," "heartthrob," "love interest," "champion," or "mastermind." If the male character fits a certain archetype, you could also use terms such as "outlaw," "rebel," "detective," or "swashbuckler" to describe him. Whatever term you choose, just make sure it accurately reflects the qualities and characteristics of your leading man.
