Broadway vet (Grace, Three Days of Rain) and Hollywood favorite Paul Rudd stopped by The Tonight Show February 25. Did he spend his segment plugging his latest movie project? Not so much. The 40-Year-Old Virgin star instead raved to Jimmy Fallon about Rocky. Turns out Rudd and his nine-year-old son are such fans of the movies that they went to the first preview of the musical adaptation that’s just started playing on the Main Stem, pictured. Watch Rudd below describe how "mesmerized" he was by the show, highlights including meat descending(!), egg drinking, the Italian Stallion Andy Karl and how the "so nice" Sly Stallone himself even gave his son a boxing lesson. You can then take a swing by the Winter Garden Theatre to see the fight of the century for yourself!
