Deane, Lucky Dog managing director Mia Jupp and head of drama Philip Palmer have all left the indie - which until last week was a joint-venture between Deane and CVE - to form Danny Rose Productions.
CVE has bought out Deane's 50 per cent stake in Lucky Dog, producer of BBC 1's A Many Splintered Thing,and the brand will be merged into the new Chrysalis Entertainment division along with other CVE brands Watchmaker Productions, Assembly Film & Television and Tandem Television.
As part of the deal, Deane is taking Lucky Dog's current ITV production, 120-minute film Back Home, starring Sarah Lancashire, with him. He will make the show under licence from Chrysalis. Jupp is producing the piece, which has just gone into pre-production, and Simon Massey is directing.
'Chrysalis is going through a process of merging its TV interests while we still cherish our independent status,' said Deane.
'It has been an entirely amicable parting. In Danny Rose [named after Woody Allen film Broadway Danny Rose] we will pick up where we left off as one of the few writer-based indies operating in quality, mainstream TV production.' He added that the new company was looking to expand its writing talent and had recently signed writer Shakil Mohammed.
Chrysalis was unavailable for comment.
