McCain Foods has selected Adam & Eve/DDB and WCRS to progress to final stage discussions in its pitch process, which kicked off in July.
This decision also means Abbott Mead Vickers BBDO and Bartle Bogle Hegarty are out of the process.
The London office of Roth Observatory International is handling the review.
A final decision is expected in the first week of October.
Trevor Beattie was instrumental in winning the McCain account in 2003 when he was the chairman of TBWA, and then capturing it again in 2006, one year after he launched BMB.
