For those who haven’t seen all of this year’s nominees for the Best Picture Oscar (and that includes just about all of us), a pair of national theater chains are looking to help out. AMC and Regal theaters around Baltimore will be showing seven of the eight nominees back-to-back-to-back. At AMC (which includes the Columbia 14, 10300 Little Patuxent Parkway; Owings Mills 17, 10100 Mill Run Circle; and White Marsh 16, 8141 Honeygo Blvd.), a marathon begins at 11 a.m. Feb 16 with “The Favourite,” followed by “BlacKkKlansman” (1:20 p.m.) and “Bohemian Rhapsody” (4 p.m.), then continues at 11 a.m. Feb. 23 with “Vice,” followed by “Black Panther” (1:30 p.m.), “A Star Is Born” (4:15 p.m.) and “Green Book” (7:30 p.m.). Tickets are $30 for day one, $40 for day two, $65-$70 for both days; sorry, tickets are not available for individual movies. (amctheatres.com.) At Regal Cinemas (including the UA Snowden Square, 9161 Commerce Center Drive in Columbia, and the Waugh Chapel & IMAX, 1419 S. Main Chapel Way in Gambrills), the seven movies will be shown daily at various times through Feb. 24; tickets are available for individual movies, or you can buy a pass to see all of them for $35. (regmovies.com.) Unfortunately for completists, the eighth Best Picture nominee, the Netflix-released “Roma,” is playing neither showcase; to see that, you’ll either have to go to the Niarchos Foundation Parkway, 5 W. North Ave., or watch it at home on Netflix.
