« Happy Days, directed by Patricia Rozema, proved to be among the less controversial films in the series, not only because she remained faithful to the script and to the basic visual imagery of the play but also because of the presence of Rosaleen Linehan as Winnie, which she had performed to much acclaim at the Gate Theatre's Beckett Festival. »
