Talisa Soto who plays Ana and Benjamin Bratt who plays Che are married in real life. They met on the set of Blood In Blood where Rene played by Jesse Borrego stars alongside Benjamin Bratt.
After Jess and his dad fight, Jess has a fat lip on the left side. A few scenes later, Jess is having his lip tended to at the home of Rene (Jesse Borrego) and the lip is swollen and bleeding on the right side.
In several of the "Cruising" scenes, the Thermador Cooler on Che's vintage car disappear and reappear several times throughout the scenes. When they show close-ups of the passenger side window, the Thermador Cooler (the tube device on top of the passenger side door) is gone, while in most of the long shots, it is back. In one close-up you can actually see the wear marks of where the cooler sits on top of the door frame where they took it off for the close up.
The memorial in Che's garage indicates his wife died in 1985. The banners in the graduation scene read "La Mission High School Class of 2009". Since it is very clear Jess was a model student, it is doubtful he would be graduating high school at the age of 24 or higher.
