BET confirmed Monday that it’s planning a miniseries about Boston boy band New Edition. Casting for the program starts locally this weekend. Boston Casting will have an open call on Saturday for actors, singers, and dancers who can play Bobby Brown, Ricky Bell, Michael Bivins, Ronnie DeVoe, Ralph Tresvant, and Johnny Gill. Those who look like the guys from age 10 to 17 should show up at 10 a.m. Those who can play them as 18- to 25-year-olds should show up at 2 p.m. The Boston Casting office is at 129 Braintree St. in Allston. Bring a current photo and prepare a minute-long monologue. Also be ready to dance and sing a New Edition song.Names can be reached at email@example.com.
