One of the bachelorettes participating in Friday night’s Project Smile Date Auction at Venu will look familiar. Lisa Oliveira, who signed up to help Project Smile (which provides toys and games to traumatized kids), has been in several films shot locally, including “Grown Ups 2,’’ in which she had a scene with Kevin James, as well as “The Heat.’’ Oliveira (inset), who’s single, said Project Smile’s date auctions have resulted in two marriages. “I hope to be the next one,’’ she said. . . . Boston Ballet Artistic Director Mikko Nissinen has announced the roster for the company’s 50th season, and it includes 11 new members and seven dancer promotions, including Ashley Ellis, who is now a principal dancer, and Dusty Button, Bradley Schlagheck, and Alejandro Virelles, who have all been promoted to soloists. Boston Ballet opens its 50th season Saturday with a free performance on Boston Common.
