LOS ANGELES—In a groundbreaking discovery that could help shed light on the evolution of fame, anthropologists from UCLA announcedThursday that they had unearthed a potential missing link between A- and B-list celebrities. “Though such a link has been hypothesized for decades, our team was able to identify a possible transitional individual, which we discovered in a recent independent film, who appears to exist between big-name, bankable movie stars and the secondary tier of supporting and small-screen actors,” said lead researcher Heather Collins, noting that any evidence linking the leading cast of Avengers: Age Of Ultron to California’s most vaguely recognizable character actors could serve as a clue to how stars have ascended the Hollywood ranks over the ages. “When considering the highest apex celebrities, such as George Clooney or Meryl Streep, we must ask: What preceded them? This missing link could be the key to understanding how a small-time cable star or bit player in films might, over time, evolve the traits of superstardom and eventually emerge to dominate the box office. The better we understand how this evolution occurs, the better we can predict the changes we’ll see on the silver screen in the Oscars seasons ahead.” Collins added that despite their findings, no evolutionary theory had yet been posited that could explain the emergence of Tobey Maguire.
