The Zendaya factor: Tom Holland’s likeability is often cited in Spider-Man success stories, but don’t underestimate his co-star (and girlfriend). This is anecdotal, but when I taught at USC Annenberg last semester, I asked which actors the students cared about. Zendaya was by far the top female choice. “Huge positives on her,” one Sony source texted me. Plus, 115 million followers on Instagram, double Holland.
