General-vote [by-による] "People's Choice Award" [subject-が] this year [also-も] announce-passive, Mel Gibson [and-と] Julia Roberts [subject-が] most popular movie actor [and-と] actress [target-に] select-passive.

News writing with stacked passives. による ('based on, by means of') is a formal compound particle formed from the verb 因る ('be due to'). Two passives (発表され, 選ばれた) suit the impersonal news register. カタカナ for loaned movie vocabulary ('ピープルズ・チョイス賞') and foreign names.
