Raiders of the Lost Ark may be known as Indiana Jones' first movie, but it also offers Alfred Molina's big debut. Before playing memorable villain, Dr. Otto Octavius, in Spider-Man 2 and Spider-Man: No Way Home, Molina took rather dramatic movie roles, appearing in many Paul Thomas Anderson films, such as Magnolia and Boogie Nights, and starring in Julie Taymor's Frida as the real-life painter Diego Rivera. He was also a popular actor on the West End too, accruing his first Olivier Award nomination for Best Newcomer in a Play in 1980 for his role in Oklahoma!
