  The description of gravitation in the framework of soliton interaction is
considered for two nonlinear field models. These models are Born -- Infeld
nonlinear electrodynamics and so-called Born -- Infeld type scalar field model.
The last model can also be called the extremal space-time film one because of
the specific form of the appropriate variational principle. Gravitational
interaction is considered in the context of unification for all interactions of
material particles. It is shown that long-range interaction of solitons of the
models appears as force one and metrical one. The force interaction can be
interpreted as electromagnetic one. The metrical interaction can be interpreted
as gravitational one.
