According to an article in digital spy
the clip we saw on Youtube with Julian and Steve in a car is the Barclaycard ad.
Green Wing actors Julian Rhind-Tutt and Stephen Mangan, who played surgeon Dr 'Mac' Macartney and anaesthetist Dr 'Guy' Guillaume Valerie Secretan in the Channel 4 comedy, are to front a new campaign for Barclaycard.
Rhind-Tutt and Mangan play two friends driving across America, living out of a car. Much like their roles in Green Wing, Mangan’s character is careless, whilst Rhind-Tutt plays a more sensible part.
Many celebrities have fronted previous campaigns for Barclaycard including Rowan Atkinson, Alan Whicker, Jennifer Aniston and most recently Jennifer Saunders.
The ads first air on ITV1 after Life Begins on October 9.
Obviously keep a look out for it, as the clip on youtube looks a little short.
