Gwyneth Paltrow on <em>Glee</em>
Remember when young Gwyneth Paltrow had a cameo in Hook? Only she wasn’t famous yet—it was her first role—so you couldn’t call it a cameo; you had to just call it what it was: featured extra. Well, she has come a long way since then—with starring roles in everything from thrillers like Seven and the period drama Shakespeare in Love, for which she won an Oscar. She also started a singing and directing career and began to inspire Glee creator Ryan Murphy as far back as his days of Popular, where he would reference her at any given chance. It wasn’t until the seventh episode of the second season of Glee, though, that Murphy got to bring Paltrow into the halls of McKinley to portray a quirky Spanish substitute teacher with unconventional methods.
