LOS ANGELES -- The Los Angeles Memorial Coliseum recently hosted two football games in two days.

The USC Trojans beat the Texas Longhorns in an overtime thriller, and less than 24 hours later, the Washington Redskins took down the Los Angeles Rams. It takes more than 1,000 people working around the clock to allow the 94-year-old stadium to pull double duty.

From field maintenance to parking enforcement to security, it's a complex operation that requires many levels of coordination and planning. More than 140,000 fans made their way to the Coliseum for the two games, and ESPN.com took an inside look at just what it takes to make it all possible.

ESPN Staff Writer This video is a time-lapse of inside the Coliseum that begins on Saturday at approximately 10 a.m., and runs for roughly 22 straight hours. It captures the preparation process leading into USC's double-overtime win against Texas and shows the field as it shifts to a surface for the Los Angeles Rams. By this time, the Coliseum is just about ready for its second game of the weekend.

ESPN Staff Writer Jay Austin is the co-owner of the Barbacoa Boyz, which operates as a catering service near Los Angeles in the city of Montrose specializing in an "eclectic combination of barbecue flavors and techniques from North, Central and South America." He starts slow-cooking the meat for his booth inside the Coliseum about 12 hours before it's supposed to be served and (in the video) explains how there is a big difference between the USC and Rams crowds.

ESPN Staff Writer 6:06 a.m.: Kickoff isn't for approximately seven hours, but the smoker at the Barbacoa Boyz stand near Sec. 27 is already hard at work.

ESPN Staff Writer Sunday, 5:56 a.m.: Here's an example of a booth that changed overnight to serve beer and wouldn't have been allowed for a USC game. At $16 per premium beer, it has to be a policy USC will at least consider changing.

ESPN Staff Writer 5:45 a.m.: What was a USC locker room just a few hours prior is now (almost) ready for the Rams.

ESPN Staff Writer Sunday, 5 a.m.: Washington Redskins employees arrive to start loading equipment into the visiting locker room.

ESPN Staff Writer Last week, they hauled away 18 tons of trash from the Coliseum. This week, there will be even more.

ESPN Staff Writer Sunday, 1:51 a.m.: They took a break from painting, but are now back out there working on the hashmarks and NFL shield.

ESPN Staff Writer Saturday, 11:43 p.m.: Almost all of the USC signage at field level has been covered up.

ESPN Staff Writer Saturday, 11:36 p.m.: By this time, the USC and visitors locker rooms have been cleared out. Rams and Redskins personnel will arrive in the morning to get everything set up for Sunday's game.

ESPN Staff Writer Saturday, 11:24 p.m.: Here's the progress they've made so far converting the field.

ESPN Staff Writer 11:10 p.m.: The removable paint used on the numbers makes it easier to spray it off during the change over. (This video is sped up 2x)

ESPN Staff Writer Saturday, 10:57 p.m.: As soon as the stadium cleared out, the grounds crew got to work painting the field.

ESPN Staff Writer Sisters Angela and Jennifer Bandich have been coming to USC games for over a decade. They've had season tickets or the Trojans and when the Rams moved back to town they grabbed season ticket for them too -- in the same seats.

ESPN Staff Writer It's the first sold-out crowd at the Coliseum for USC since 2013. Great atmosphere.
