The most complex effect of Species II (1998) was the monstrous alien form of the infected astronaut Patrick. Producer Frank Mancuso wanted to avoid obvious digital effects for the monsters, thanks to negative reaction to the digital Sil in the first film.
XFX realized the Patrick alien as a performer in a very elaborate creature suit fitted with leg extensions, puppeteered false front legs, and held on a wire harness like a marionette.
