Brown will play the lead in BBC One's new drama By Any Means, from writer Tony Jordan (Life On Mars, Hustle).
"I play a character called Jack Quinn, who's in charge of a team and their brief is to catch criminals by any means," Brown told Digital Spy. "It's of the crime genre, but they're not actually police. They go after criminals that the police can't catch, for whatever reason.
"It's a bit of a dysfunctional family - different members of the team have different skills and they're called upon when required.
"I tried to describe it and I said, 'It's like The A-Team meets The Equalizer', and then I thought, 'I would absolutely bloody watch that!''
Brown also explained that By Any Means is lighter fare than his recent work on the BBC's Luther and Good Cop.
"I've done some fantastic work with Luther and Good Cop, but I've not really been smiling that much for four years!" he joked.
"By Any Means - it is serious, but there's a lot of fun to be had in it, as well. It's quite caper-ish and there's a lot of banter between the team."
Shelley Conn (Terra Nova), Andrew Lee Potts (Primeval) and Elliot Knight (Sinbad) will also star in By Any Means.
