The aim of this paper is to develop a representation of control that does not require a
PRO-subject. I first analyse obligatory control using a de-compositional analysis of theta-roles,
according to which theta-roles are divided into two selectional requirements. The
resulting theory makes the same predictions as one based on PRO, yet avoids
dependence on this ill-defined empty category. I then concentrate on Icelandic,
tackling agreement phenomena in infinitival clauses. Again no PRO is necessary to
answer for the data, which receive a uniform account using the mechanism outlined in
the first half of the paper
