[2] The 687-seat theatre[3]: 286  was a venue for more intimate productions, and was often leased to producers including William Collier, Cecil B. DeMille, and the Washington Square Players.

[3]: 286–287  When the Mercury took over the theatre, production manager Jean Rosenthal presented Houseman with "a formidable list of absolute and immediate necessities, which included major repairs to the grid, new rigging and power lines and a new stage floor to replace the rotting planks through which huge, fearless rodents could be seen emerging on their hunting excursions."

[9] Richard Linklater's 2008 film, Me and Orson Welles, is a romantic comedy set during the days before the opening of Caesar at the Mercury Theatre.

"Like most Welles stage shows, alas, this one left few traces," wrote Wall Street Journal drama critic Terry Teachout.

… What makes Me and Orson Welles uniquely interesting to scholars of American drama is that Mr. Linklater's design team found the Gaiety Theatre on the Isle of Man.

Then Mr. Linklater filmed some 15 minutes' worth of scenes from the play, lit according to Jean Rosenthal's plot, accompanied by Marc Blitzstein's original incidental music and staged in a style as close to that of the 1937 production as is now possible."
