Need help deciphering dialogue on this panel

[GoggledAnon]

I need help with this panel from chapter 7 of The Two of Them Are Pretty Much Like This. Scribbly kanji is one of my weak points and it's even harder when it's mushed together and partially obscured like this. If anyone knows how to translate it or at least can transcribe the JP text for it, that'd be really helpful, since we have chapter 8 already typeset for release.

Chapter for context

Fourth bubble is possibly 犬/大（？）のウンコ踏靴でそのゾウリの恵と見分けの〇かねェッ

Seems like some of the words were cut off. Like in the top left bubble, I don't know what could 仕体張 mean.

@GoggledAnon
Just my guess since there're some hidden and shorten word

1st bubble「クッソタレ、なあ〜に〇〇劇場版で主役(デローじゃシューも？）」I'm really not sure what the last part is

2nd bubble 「ヘイヘイ事務所じかくてよござしたねぇ」Weird grammar but that should be it

3rd bubble 「マイナーソシェだって仕事は仕○体張っせや」 ソシェ probably refer to ソサイエティ. There should be another kanji after 仕, probably 仕上に？ 体を張る means dedicate yourself

4th bubble as pnutz said, the ○ probably just つ
