House viewers have heard a lot about Foreman's past, but fans are about to actually meet one person from it.

Sources confirm to Michael Ausiello that Orlando Jones has been cast as Foreman’s estranged (and currently imprisoned) brother, Marcus.

The episode with Marcus has already been shot and will air in February. It will find the the siblings reconnecting, on the eve of Marcus’ parole hearing, but only briefly.

A disagreement will ensue and a major development will take place as a result.

On the small screen, Jones has appeared most recently on Pushing Daisies, Rules of Engagement and Ghost Whisperer.
