 Filming on " Extinction " began on July 31 , 2003 , with a shoot that lasted the following seven working days . To represent the jungle of the alien planet , the soundstage was inundated with foliage . A Xindi landing pod was created to appear in those same scenes . Several of the main cast were required to undergo extended make @-@ up sessions lasting three or four hours every day for six days of the shoot in order for their characters to appear in a number of different stages of mutation . The make @-@ up on Jolene Blalock was not as extensive as that on Scott Bakula , Dominic Keating and Linda Park due to her character 's Vulcan anatomy . Both Bakula and Keating had to wear bladders on their throats as a special effect which were inflated when they growled . Following the experience , Park praised John Billingsley , who in his role as Doctor Phlox has to undertake similar make @-@ up regimes for every episode .
