LOS ANGELES—On Monday, actor David Schwimmer began filming for Can't Help Myself, a Buena Vista Pictures romantic comedy that promises to be yet another big-screen bomb starring a Friends cast member. Slated for December release, Can't Help Myself will join such previous Friends-star-driven bombs as Picture Perfect, Ed, Fools Rush In, The Pallbearer, Kissing A Fool, 'Til There Was You, Romy And Michele's High School Reunion, and She's The One, as well as such soon-to-be-released bombs as Jennifer Aniston's Object Of My Affection and Courteney Cox's Alien Love Triangle.
