In 2004, Walsh directed The Big Bow Wow for RTÉ. The following year, she directed Funland for BBC Three, and in 2006, she directed the four-part RTÉ drama series Hide and Seek. The first episode was described as "extremely stylish visually" by Liam Fay in The Sunday Times. At the end of the series, Fay commented that "the first three programmes were painfully slow" and "the closing installment seemed, at times, to grind to a halt," noting that "much of it was filled with vast arctic silences as distraught characters stared meaningfully at each other."
