What would Comic-Con be without celebrities? Pretty boring, we think. Thankfully, Hollywood showed up in a big way this year, and Friday proved to be a huge day for star gazing.
Here’s a list of stars — A-listers and otherwise — spotted at Comic-Con.
Comic-Con 2025: These were some of the celebrity sightings Thursday in San Diego

Fun fact: In 2017, a street in Clairemont — at the corner of Castleton Drive and Mount Abernathy Avenue — was renamed “Mark Hamill Drive.” That’s the San Diego neighborhood where the “Star Wars” star lived with his family.
