“Saturday Night Live” player and “Ghostbusters” reboot star Leslie Jones performed a surprise stand-up set at Laugh Boston Saturday night. She joined a lineup that included 2010 “Last Comic Standing” winner Felipe Esparza and Worcester’s own Orlando Baxter. The VIPs in the audience were “Ghostbusters” director Paul Feig, Jones’s “SNL” and “Ghostbusters” costar Kate McKinnon, and Steve Higgins from “The Tonight Show Starring Jimmy Fallon.” The new “Ghostbusters,” which also stars Kristen Wiig, started filming around Boston last week.
