America’s most famous film critic, Roger Ebert, passed away Thursday, April 4 after a 10-year struggle with thyroid cancer. During his 70 years on earth, the movie fanatic wittily and enthusiastically shared his passion with the world, as evidence by his widely successful “At the Movies with Siskel and Ebert” series, thousands of reviews for “The Chicago Sun-Times” and a Pulitzer Prize for his stellar reporting.
