Green Lantern grabs Angela Bassett

Actress signs on as Dr Amanda Waller...

Oscar-nominated actress Angela Bassett has joined the cast of the currently-shooting Green Lantern .

The star of Malcolm X and Boyz n The Hood will play Dr Amanda Waller, who appears in the original DC Comic. Waller is a former congressional aide who oversees the Suicide Squad, a shadowy government group of ex-supervillains.

Also signing up late to the cast is nine-year-old Gattlin Griffith ( Changeling , Couple’s Retreat ), who is reportedly shooting just 12 days on the film as a character called Robert.

No word who this Robert is, though various sites have speculated that he could be a codename for a young Hal Jordan – especially considering a younger version of beau Carol Ferris has been cast in the form of Jenna Craig.

These two join Ryan Reynolds, Blake Lively, Mark Strong, Tim Robbins and Peter Sarsgaard, with the film currently shooting in New Orleans under director Martin Campbell.
