'Desperate Housewives' Square Off Against Nicollette Sheridan

Marc Cherry is not Nicollette Sheridan's only adversary in her trial -- her former co-stars are poised to destroy her case, because they're all set to testify for the defense.

TMZ has obtained the witness list in Nicollette's trial.  Among those who will be called on behalf of Cherry -- Eva Longoria, Felicity Huffman, James Denton, Marcia Cross and Neal McDonough.

The women on the show will all testify -- they never saw Marc strike Nicollette, as she alleges, nor did they witness any retaliation after she complained to ABC honchos.

According to the witness list, Nicollette wants to grill Marc for 8 hours. 

Eva, Felicity, James, Marcia and Neal will all be in and out in 30 minutes or less, although cross-examination could prolong things.
