"Marketing is what gets you noticed, and that side of it something - this side of it, if you like, doing interviews - is the side of it that I least enjoy, and yet is 50% of the project"

Rowan Atkinson is suggesting that marketing is an essential part of any project, as it is what gets you noticed. However, he also acknowledges that the other side of the project, such as doing interviews, is something he least enjoys. He is emphasizing that this side of the project is just as important as the marketing side, as it makes up 50% of the project. This quote highlights the importance of both marketing and the other aspects of a project, and how they are both equally important for the success of the project. It also shows that even though marketing is important, it is not the only factor that contributes to the success of a project.
