Arrow type TV Show network The CW genre Superhero

Want to meet Laurel Lance’s missing mother?

Former ER series regular Alex Kingston is joining The CW’s breakout superhero drama Arrow in a recurring guest star role. The British actress will play Dinah Lance — Laurel’s (Katie Cassidy) mom and Detective Quentin’s (Paul Blackthorne) ex-wife. Later this season Dinah will return to Starling City to make amends with her family that she abandoned years earlier following the tragic death of her daughter aboard Oliver Queen’s (Stephen Amell) yacht.

In addition to her years on ER, Kingston recently earned some serious geek cred in a recurring role on the BBC’s Doctor Who playing River Song — so now Arrow has nabbed both Capt. Jack (John Barrowman) and River from that ‘verse.

Arrow returned to Wednesday nights last week after its winter break to deliver a ratings gain, which is always great to see.
