The actor, who has gone on to have huge success in the US since leaving the soap 10 years ago, will be reprising his role as Sean Slater for a short stint in the spring.
These days, he’s probably better known to fans as Chuck Hansen in Guillermo del Toro’s ‘Pacific Rim’, Warlow in ’True Blood’, Orgrim Doomhammer in the film ‘Warcraft: The Beginning’ and for playing the lead role in Fox drama ‘Second Chance’.
However, Rob will return to what he calls his “home” during a gap in his US schedule to tie up some “unfinished business” and to say “thank you” to the show for starting his career.
He said: “EastEnders is still the most important serial on British television, never afraid to combat hard storylines and tell hard truths.
“I have always been proud of what EastEnders has done for social awareness throughout my lifetime and that is why I’m back.
“To tell a story that means something to me with the family that I know can tell it right.
“I can’t wait to see my Slaters again and see what’s in store for Sean as he brings an evolved animal to Albert Square.”
He added: “I have unfinished business in Albert Square and am thrilled to be returning to what I still consider to be my home, however briefly.”
Rob later posted on Twitter: “It’s something I always wanted to do to say thank you to Sean and the show, and we have worked to fit it in in the most explosive way.”
Rob made his first appearance as the brother of Stacey Slater in 2005, with Sean being involved in many memorable storylines during his four-year stint, including romances with Ruby Allen and Tanya Branning.
He was last seen on New Year’s Day in 2009 when he kidnapped Roxy Mitchell’s daughter Amy, after discovering he was not actually her father.
A showdown saw him and Roxy plunge through the ice of a frozen lake, and after escaping, he left Walford for good.
Sean will have plenty of catching up to do when he arrives back on Albert Square, with his sister Stacey, mum Jean, and relatives Mo, Kat and Hayley all currently residing in Walford.
