We show that Wigner's infinite spin particle classically is described by a reparametrization invariant higher order geometrical lagrangian. The model exhibits unconventional features like tachyonic behaviour and momenta proportional to light-like accelerations. A simple higher order superversion for half-odd integer particles is also derived. Interactions with external vector fields and curved spacetimes are analyzed with negative results except for (anti) de Sitter spacetimes. We quantize the free theories covariantly and show that the resulting wave functions are fields containing arbitrary large spins. Closely related infinite spin particle models are also analyzed.
