MGM is looking to open up shop with Ice Cube, as the studio is in negotiations with the multi-hyphenate to reprise his role of Calvin in Barbershop 3.  In addition to Cube, the aim is to land deals with Cedric the Entertainer and Queen Latifah to return to play Eddie and Gina respectively.  The Entertainer appeared in both 2002's original Barbershop and the 2004 sequel, Barbershop 2: Back in Business.  Latifah starred in the sequel, and followed it up with a lead role in the spin-off film, Beauty Shop.  There are no plot details available at this time, but as Deadline reports, the search is on for writers.
