We introduce a new class of non-isothermal models describing the evolution of nematic
liquid crystals and prove their consistency with the fundamental laws of classical
thermodynamics. The resulting system of equations captures all essential features of
physically relevant models; in particular, the effect of stretching of the director field is taken
into account. In addition, the associated initial-boundary value problem admits global-in-time
weak solutions without any essential restrictions on the size of the initial data.
