If you live in the United States and love the films of Hayao Miyazaki, Roger Ebert is a big reason you can watch the films of the master in a theater or on DVD. Years before the internet became a household utility, most people who would become anime lovers relied on a tiny section of their local video rental store, which might contain Akira, Ghost in the Machine, Heavy Metal (which isn't anime but always ended up in that section anyway), and if you were really lucky, a Tenchi Muyō! OVA.
That started to change when in 1993, when Miyazaki's English-dubbed My Neighbor Totoro appeared under the radar on American video shelves. Ebert devoted a special segment of his show to recommending My Neighbor Totoro to an American audience who'd most likely never heard of him. It's interesting to see Ebert talk about a Ghibli film for the first time and describe it to an audience that probably has no idea what he's talking about. Ebert would champion other Miyazaki films such as Princess Mononoke and Ponyo, and would write Great Movie essays about Totoro, Spirited Away and the non-Miyazaki classic Grave of the Fireflies (along with showing Metropolis at his film festival). Ebert's voice carried to millions of Americans who might never have checked out a Miyazaki film, and helped introduce his work to a wider audience.
