Film genres can be flexible, and artistic expression isn't always limited exclusively to comedic or serious themes. Many actors have successfully transitioned from one genre to another throughout their careers but comparing one actor or comedian for working in only one type of role doesn’t give credit for their versatility outside of acting talent.
Ultimately, what makes a great artist is the ability to communicate a message effectively through their art. Whether that message is conveyed through humor, drama, romance or suspense is largely subjective and ultimately it's the audience opinion that matter when movies get made into art history books.
